8021q: fix a potential use-after-free
[ Upstream commit 4a7df340ed1bac190c124c1601bfc10cde9fb4fb ]
vlan_vid_del() could possibly free ->vlan_info after a RCU grace
period, however, we may still refer to the freed memory area
by 'grp' pointer. Found by code inspection.
This patch moves vlan_vid_del() as behind as possible.
