Tim Yi 446ff1fc37 net: bridge: vlan: fix memory leak in __allowed_ingress
[ Upstream commit fd20d97383 ]

When using per-vlan state, if vlan snooping and stats are disabled,
untagged or priority-tagged ingress frame will go to check pvid state.
If the port state is forwarding and the pvid state is not
learning/forwarding, untagged or priority-tagged frame will be dropped
but skb memory is not freed.
Should free skb when __allowed_ingress returns false.

Fixes: a580c76d53 ("net: bridge: vlan: add per-vlan state")
