qcacld-3.0: Avoid crash when psoc trans is rejected
Crash is seen when the mode change and shutdown happens in
parallel. Mode change is the driver trans and shutdown is a
psoc trans. If mode change is going on and shutdown req comes
then shutddown trans is rejected. Currently driver crashes
whenever psoc trans is rejected.
Avoid BUG_ON when the psoc trans is rejected.
