mac80211: Prevent AP probing during suspend
Submitting AP probe/null during suspend can cause unexpected
disconnect on resume because of timeout waiting for ack status:
wlan0: Failed to send nullfunc to AP 11:22:33:44:55:66 after 500ms, disconnecting
This is especially the case when we enter suspend when a scan is
ongoing, indeed, scan is cancelled from __ieee80211_suspend, leading
to a corresponding (aborted) scan complete event, which in turn causes
the submission of an immediate monitor null frame (restart_sta_timer).
The corresponding packet or ack will not be processed before resuming,
causing a timeout & disconnect on resume.
Delay the AP probing when suspending/suspended.
