wlan: Check for WatchDog reset status during queue selection

Check for the WatchDog reset status during queue selection request,
If WD reset in progress, then return the Best Effort queue index.
Else derive queue index based on the current session parameter and
return.

This avoids any access to the internal data structure during
reset.
