Rafał Miłecki 17501f822f mac80211: backport ieee80211_vif_is_mld()
It's needed by some drivers, e.g. mt7925, see:
mt7925/mcu.c:2181:23: error: implicit declaration of function 'ieee80211_vif_is_mld' [-Werror=implicit-function-declaration]

Subject: [PATCH] wifi: mac80211: implement proper AP MLD HW restart
Previously, I didn't implement restarting here at all if the
interface is an MLD, so it only worked for non-MLO. Add the
needed code to restart an AP MLD correctly.
