wlan: memory corruption fix

During unload WLAN driver, MSG Q flushing routine will free memory
which is not dynamically allocated.
Then memory area corruption happpen, and when next load driver,
corrupted memory will be allocated, as a result system crash happen.
Not to free static memory location, MSG body for MC thread WDI Q
will not be freed, and will print message type which made problem.
