wlan: Handle fatal events based on FW capability

IF FW doesn't supports FATAL EVENTS then as part of DXE done
indication it sends reason code as zero and this may lead to
failure in processing fatal events, as host assumes reason code
will be non-zero for FATAL events.
Hence changes done to process fatal events appropriately based on
FW capability.
