mac80211: complete scan work immediately if quiesced or suspended
It is possible that a deferred scan is queued after the queues are flushed in __ieee80211_suspend(). The deferred scan work may be scheduled by ROC or ieee80211_stop_poll(). To make sure don't start a new scan while suspending, check whether we're quiescing or suspended and complete the scan immediately if that's the case.
