mac80211: Don't restart sta-timer if not associated.
I found another crash when deleting lots of virtual stations
in a congested environment. I think the problem is that
the ieee80211_mlme_notify_scan_completed could call
ieee80211_restart_sta_timer for a stopped interface
that was about to be deleted.
With the following patch I am unable to reproduce the
crash.
