From: Davide Caratti <dcaratti@redhat.com>
[ Upstream commit 5a4931ae0193f8a4a97e8260fd0df1d705d83299 ]
Similarly to what was done with commit a52956dfc503 ("net sched actions: fix refcnt leak in skbmod"), fix the error path of tcf_vlan_init() to avoid refcnt leaks when wrong value of TCA_VLAN_PUSH_VLAN_PROTOCOL is given.
