Felix Fietkau 7eeabcea79 wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes
commit 4f2bdb3c5e3189297e156b3ff84b140423d64685 upstream.

When moving a station out of a VLAN and deleting the VLAN afterwards, the
fast_rx entry still holds a pointer to the VLAN's netdev, which can cause
use-after-free bugs. Fix this by immediately calling ieee80211_check_fast_rx
after the VLAN change.
