Currently, driver sends NAN enable/disable request to firmware
and waits for the response. NAN state is cleaned up when NAN
disable indication is received. But if firmware doesn't respond to
NAN enable or disable request, a timeout happens and NAN state is
not cleaned up.
Cleanup the NAN state upon timeout for NAN enable/disable request.

NDI delete response is sent to userspace only when NDI is in
NAN_DATA_NDI_DELETING_STATE state. But NDI could be in
NAN_DATA_DISCONNECTED_STATE state if cleanup happens through
NDP_END_ALL path. Driver doesn't send response to userspace in
this case.
Send the response to userspace in NAN_DATA_DISCONNECTED_STATE also
as the application might be waiting for NDI delete status.
Also, use set/get APIs and avoid accessing NDI state directly.

When NDI is removed from framework, driver deletes all NDPs
as part of eWNI_SME_STOP_BSS_REQ. Driver posts WMA_DELETE_STA_RSP
to lim from wma just after sending PEER_DELETE request to
firmware for NDP and ignores the DEL_STA response from firmware.
If there are multiple peers, all peer delete requests are sent
back to back to firmware. NDI peer delete and NDI VDEV delete
request also follow these immediately. All these commands
can go back to back to firmware as driver doesn't wait for
any of these responses.
But firmware needs some time to send NDP end frame to
the NDP peer after receiving NDP peer delete. Firmware might hold
the NDP peer delete request till it successfully sends the frame
to the peer.
Driver must wait till the NDP peer delete response is received to
proceed further with NDI cleanup/NDI vdev delete.
So, send NDP_END_ALL to firmware to let the firmware
initiate cleanup for all NDP peers. Use ucfg_nan_disable_ndi to
do the same which takes care of waiting for response from firmware
indicating cleanup has started. Then wait for all NDP END
indications and unblock the wait upon receiving last NDP END
indication.

Firmware advertises the NAN separate vdev capability through
the service capability wmi_service_nan_vdev and host advertises
through the ini param nan_separate_iface_support. Both of the
capabilities must be checked to support the NAN separate vdev
support. Define an API to check both the capabilities and made
the individual capability APIs static. So that individual APIs
are not accessed outside this common API. Use this API to
know the support. This is to avoid any possible misses in
checking the support.
For example, NAN vdev id is fetched from the NAN enable
response message received from firmware only based on
firmware capability in nan_handle_enable_rsp. If firmware
supports the feature and ini is set to 0, then vdev id might
be invalid as it's fetched from the NAN enable response
without considering host capability. If either firmware or
host doesn't support NAN separate vdev feature, firmware
creates vdev and it may not fill the vdev id in NAN enable
response. Host shall use NAN_PSEUDO_VDEV_ID then.
So, consider NAN separate vdev feature as supported only if
both host and firmware support.
Also fetch the firmware capability to support NAN separate vdev
when wma_rx_service_ready_ext_event is received and update to NAN
psoc priv object.

Currently in case of STA+NDI+NDI concurrency, the below scenario
can occur,
1) If NDI(NDP) + NDI(NDP) exists and sta tries to connect,
then all NDPs on 1st NDI is tear down.
2) If STA+NDI(NDPs) exist and then another NDI tries to establish
the NDP, then it is allowed in the current driver.
Fix is to reject the 2nd NDI(NDP) if STA+NDI(NDPs) concurrency
already exist.

There is a race condition while handling the below scenario,
1. NAN enable request is received from framework.
2. Policy mgr opportunistic timer expired and set hw mode
initiated to Single MAC mode in scheduler thread at
the same time
As the opportunistic timer handler doesn't have any info if
NAN enable initiated in DBS mode, it's configuring the hw
mode to Single Mac Mode just before NAN enable request is sent
to firmware. So the NAN enable request is sent to firmware in
Single Mac Mode which is not allowed by firmware.
NAN enable/disable is also similar to connection in progress
status in case of STA. So provide NAN enable/disable status
through hdd_is_connection_in_progress() to the opportunistic
timer handler. Opportunistic timer handler restarts the timer as
connection(NAN enable/disable) is in progress.
Also set hw_mode_change_in_progress before checking the
connection progress status. This is to avoid a possible race in
the below scenario,
1. NAN-enable sets the state but scheduler thread had read the
state just before that
2. NAN-enable read the hw_mode_change_in_progress just
before it gets set by scheduler thread.

In the host driver, after receiving NDP END INDICATIONs for all NDP
connections then policy manager deletes NDI mode from
pm_conc_connection_list.
From user-space application, if NDP END REQUEST and NDI DELETE request
are issued back to back without waiting for NDP END indication, then
firmware could process NDI DELETE command firstly and avoid NDP END
indication due to peer delete as a part of NDI delete.
If vendor command NDI delete request is issued without receiving
NDP_END_INDICATIONs for all active NDP peers then pm_conc_connection_list
contains stale entry of PM_NDI_MODE associated with deleted NDI.
Stale NDI entry in pm_conc_connection_list is the cause for failure of
get_second_connection_pcl_table_index() for PM_NAN_DISC_MODE, therefore
further NAN enable requests are rejected.
To address this issue, cleanup PM_NDI_MODE from pm_conc_connection_list
as a part of NDI delete.
