Artem Savkov 90e0970f87 cfg80211: sched_scan_mtx lock in cfg80211_conn_work() 
Introduced in f9f475292d
("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:
