net/sched: fix refcnt leak in the error path of tcf_vlan_init()
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. Fixes: 5026c9b1bafc ("net sched: vlan action fix late binding") CC: Roman Mashak <mrv@mojatatu.com> Signed-off-by: Davide Caratti <dcaratti@redhat.com> Acked-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: David S.
