The platform driver will not allow the WLAN SoC to be removed if a
firmware down indication has been received. However, the firmware down
indication can be received in a hardware interrupt context, and so must
never block. This makes it impossible to add appropriate synchronization
to the firmware down indication handler. This all culminates in a
situation where any check to see if recovery is in progress by the WLAN
driver during rmmod will always be racy and be susceptible to deadlock.
Move remove outside of the protection of the rmmod transition, instead
protecting remove with its own transition. This relies on the platform
driver to do the serialization with recovery itself, removing the
recovery-in-progress check from WLAN.
This fix is _not_ multi-SoC compatible. However, the current platform
driver/wlan driver interface is not multi-SoC compatible either. When
this API is reworked to add multi-SoC support, this issue will need to
be revisited.

With kernel version 4.19, a new structure
cfg80211_fils_resp_params is introduced for fils parameters in
the existing structure cfg80211_connect_resp_params. The
functions hdd_populate_fils_params and hdd_connect_done use
cfg80211_fils_resp_params as argument for modifying the fils
parameters. This causes compilation issues with 4.19 kernel.
Add changes to accumulate cfg80211_fils_resp_params structure
addition from 4.19 kernel.

When roaming is completed if the phymode of the target AP is
different from current phymode, then firmware will have updated
phymode and host driver will have older phy mode. The host driver
will update the opmode when new opmode is found over beacon or
vht opmode action frame. During opmode updation over
wma_process_update_opmode(), phymode is also sent to firmware.
As the phymode on the host driver is not updated to new value
after roaming and there will be mismatched phymode sent to
firmware. Firmware will not be able to handle this and asserts.
With current design, the channel width and frequency are updated
to wma interface on roam synch complete. Fix is to update the
phymode also after roam synch complete is received to wma iface
based on the new channel width updated.

Currently, value of staIndex in dph hash table is not getting
updated after roaming. But diver invokes pe_find_session_by_sta_id
to get PE session to handle eWNI_SME_GET_TSM_STATS_RSP. Due to a
different value of staIndex and staid, session lookup fails for
StaId. This results in failure of IOCTL command "GETTSMSTATS"
after roaming.
Fix is to use bssid instead of sta id to find session in
lim_send_sme_pe_ese_tsm_rsp.

Analysis:
1. Host initiated deauth and queued WLAN_SER_CMD_FORCE_DEAUTH_STA.
2. During deleting the STA, updated
sta_ds->mlmStaContext.cleanupTrigger as
eLIM_HOST_DISASSOC(0), default is 0.
3. At same time, the assoc req was received for this STA on other
vdev, in lim_check_sta_in_pe_entries() driver update
sta_ds->mlmStaContext.cleanupTrigger to eLIM_DUPLICATE_ENTRY.
4. lim_prepare_and_send_del_sta_cnf-> lim_send_del_sta_cnf()
use sta_ds->mlmStaContext.cleanupTrigger to update
mlmDisassocCnf.disassocTrigger to eLIM_DUPLICATE_ENTRY
instead of eLIM_HOST_DISASSOC.
5. Thus in lim_send_sme_disassoc_ntf(),
eWNI_SME_DISCONNECT_DONE_IND was called instead of
eWNI_SME_DISASSOC_RSP.
6. Thus we tried to remove WmStatusChange instead of
WLAN_SER_CMD_FORCE_DEAUTH_STA.
Fix:
Reject assoc req instead of using eLIM_DUPLICATE_ENTRY logic if
STA is already being deleted.
