wlan: Replace VOS_BUG with SSR

Replace VOS_BUG with SSR in case of tx timeout, Thread Stuck
and sme out of buffer.

In Internal builds SSR is not enabled so this will lead to
same behaviour as VOS_BUG. In customer builds SSR is enabled
so the driver will recover from this condition using SSR
and will not cause crash.

Also if fatal events are enabled, once fatal event is completed
do SSR in case reason of fatal event is tx timeout, active
command timeout or sme out of buffer.
