In the driver, if CLUB_LL_STATS_AND_GET_STATION feature is
enabled, host requests Link Layer stats and station stats
from firmware periodically using a single WMI command.
Host then sends LL_STATS to userspace and caches station stats
in the adapter. Whenever userspace queries station stats, based
on the sta_stats_cached_timestamp, host returns cached stats
from adapter instead of sending a new WMI request.
The current issue, as part of station stats firmware also sends
connection_tx_power stats, which aren't cached into the adapter.
So, whenever userspace queries get_tx_power via nl commands,
host sends a WMI request to firmware for tx_power leading to
platform wakeups and power impacts.
To resolve this issue, cache the tx_power sent by firmware into
the adapter during station stats and return the cached value to
the user space.

Host driver rate limits successive get_txpower
calls within 3 seconds, and sends cached stats
from the hdd_stats. However, max_tx_power is
not updated in the hdd_stats. Therefore,
the cached tx power is always 0 dBm.
Also, the hdd_stats would be only updated when
CP stats are received from the firmware for
get_station/dump_station calls. get_station is not
periodically queried for SAP interface from the
framework. Therefore, tx power for SAP interface will
always be 0 even if hdd_stats gets updated.
To fix this, instead of hdd_stats, return the
max tx power from the pdev stats cached on the pdev.

Scenarios are:
1. Host receives ROAM_START from firmware
2. Host receives EAPOL M1 from AP, host forwarded
it to supplicant and supplicant buffered it (with
timer 100 msec) to process it after association
completion.
3. Host starts processing CP stats request, which
holds RTNL kernel lock
4. Host starts a CP_STATS_WAIT_TIME_STAT (800 msec)
timer and sends WMI_REQUEST_STATS_CMDID to FW.
So cp stats are holding the RTNL lock.
5. In waiting state host/FW completed roaming within
a few milliseconds. Host Call roamed indication
to the kernel. Kernel post it to the Work queue
to indicate this to the supplicant. The Work
queue requires the RTNL lock to send the
indication to the supplicant.
6. Now Kernel is waiting on the RTNL lock taken by
the CP stats request which is waiting for the CP
stats response (WMI_UPDATE_STATS_EVENTID).
7. Host receives CP stats response but the host is
unable to handle it with the below reason.
8. Timed out happens for WMI_UPDATE_STATS_EVENTID,
then Kernel takes RTNL lock to indicate
association/roam completion status to the
supplicant.
9. As Kernel is sending association indication
after CP_STATS_WAIT_TIME_STAT (800 msec), by
this time supplicant deleted buffered EAPOL
first frame, this results in DUT failing to
initiate the 4-WAY handshake.
10. Finally AP sends the Deauthentication frame
to DUT.
Reason for unable to process CP stats response :
As per the current design, While processing Roaming,
the host deletes the old peer and creates a new peer
for roamed AP. If the Host receives cp stats response
after peer delete due to roaming, the host is unable
to stop waiting for timer CP_STATS_WAIT_TIME_STAT
and fails to release RTNL kernel lock till timeout.
After time out only, Kernel can take RTNL lock to
indicate association/roam completion status to the
supplicant.
Fix is to stop the wait timer CP_STATS_WAIT_TIME_STAT
and release RTNL kernel lock even in case peer has
deleted by HOST for which CP stats request sent.

Cmd of WLAN_SER_CMD_GET_DISCONNECT_STATS will never be
