" ath10k: Pause the tx queues when firmware is down"
This is done only for SNOC (wcn3990) target and does not affect other
targets.

" ath10k: Skip wait for delete response if firmware is down"
The skip for wmi responses is done based on the flag
"ATH10K_FLAG_CRASH_FLUSH", which is generic for all targets.
Since if the FW is down, there wont be any response from the FW for any
target.
