mac80211: don't clear sched_scan_sdata on sched scan stop request
ieee80211_request_sched_scan_stop() cleared local->sched_scan_sdata. However, sched_scan_sdata should be cleared only after the driver calls ieee80211_sched_scan_stopped() (like with normal hw scan). Clearing sched_scan_sdata too early caused ieee80211_sched_scan_stopped_work to exit prematurely without properly cleaning all the sched scan resources and without calling cfg80211_sched_scan_stopped (so userspace wasn't notified about sched scan completion).
