Assuming sched_scan_stop operation is synchronous the driver may not
necessary call ieee80211_sched_scan_stopped_work. Since this work is
the only place where sched_scan_sdata is released we can possibly run
into situation when it is never released. Fix this by releasing it
just after calling drv_sched_scan_stop.
