cfg80211: sched_scan_mtx lock in cfg80211_conn_work()
Introduced in f9f475292dbb0e7035fb6661d1524761ea0888d9
("cfg80211: always check for scan end on P2P device")
cfg80211_conn_scan() which requires sched_scan_mtx to be held can be called
from cfg80211_conn_work(). Without this we are hitting multiple warnings like
the following:
