This patch fixes the following warning:
WARNING: suspicious RCU usage
[ 84.530619] 5.6.0+ #4 Not tainted
[ 84.530637] -----------------------------
[ 84.530658] net/mac80211/scan.c:454 RCU-list traversed in non-reader section!!
As local->mtx is held in __ieee80211_scan_completed(), no need to use
list_for_each_entry_rcu() (use list_for_each_entry() instead.).
