mac80211: fix beacon loss detection after scan
Currently beacon loss detection triggers after a scan. A probe request
is sent and a message like this is printed to the log:
wlan0: beacon loss from AP 00:12:17:e7:98:de - sending probe request
But in fact there is no beacon loss, the beacons are just not received
because of the ongoing scan. Fix it by updating last_beacon after
the scan has finished.
