qcacld-3.0: Flush pending scan queue during con mode handling

Currently, Host is operating into STA (mission mode) and scan
is pending into the pending queue. As a part of the mission
mode to ftm transition scan pending queue is not flushed. Hence
later during driver unload, host try to flush this pending
request but sta adpater is already freed during con mode
transition which lead to kernel panic.
As a part of this fix, Host ensures to flush pending scan
queue during con mode handling.
