ath10k: Fix the race condition in firmware dump work queue
There is a race condition, when the user writes 'hw-restart' and
'hard' in the simulate_fw_crash debugfs file without any delay.
In the above scenario, the firmware dump work queue(scheduled by
'hard') should be handled gracefully, while the target is in the
'hw-restart'.
Tested HW: QCA9984
Tested FW: 10.4-3.9.0.2-00044
