net: openvswitch: don't unlock mutex when changing the user_features fails
[ Upstream commit 4c76bf696a608ea5cc555fe97ec59a9033236604 ]
Unlocking of a not locked mutex is not allowed.
Other kernel thread may be in critical section while
we unlock it because of setting user_feature fail.
Fixes: 95a7233c4 ("net: openvswitch: Set OvS recirc_id from tc chain index")
