qcacld-2.0: fix the null pointer access issue when shutdown
This issue is caused by the NULL pointer access when do wlan driver
shutdown and do the process of wlan connecting operation in driver
at the same time. In this case, the driver is processing connecting
and there is a timer started, and if it expired before this timer
destory when do PE stop, it will wakeup the MC thread and continue to
process it, but if some related resource freed during the shutdown
before the MC thread stop, this NULL pointer access will happen.
So skip to process messages in MC thread if doing shutdown and this
issue will not happen in this case.
