qcacld-3.0: Extend WMA_RESUME_TIMEOUT to 25 secs
If WLAN FW crashes while in suspend mode then kernel tries to
resume the driver and WMA sends resume indication to WLAN FW and
waits for the response from WLAN FW. Since FW is already crashed,
there will not be any response from WLAN FW and wait logic waits
for the timeout before bailing out. This may cause delay in
completing the recovery and may cause other race conditions
becuase of that. To solve this, we registered for shutdown
notification so that call back would be called during recovery
and resume event can be set to make sure resume thread doesn't
just wait for the FW response. However, it takes around 7 ~ 12 secs
for platform driver to receive PD down notification and trigger
the recovery but wma only waits for 6 secs and still crashed
before recovery started. The fix it to extend WMA_RESUME_TIMEOUT
to 25 secs so that it can be interrupted gracefully by recovery
call backs.
