Paolo Abeni ca2c1418ef udp: drop head states only when all skb references are gone ... After commit 0ddf3fb2c4 ("udp: preserve skb->dst if required for IP options processing") we clear the skb head state as soon as the skb carrying them is first processed. Since the same skb can be processed several times when MSG_PEEK is used, we can end up lacking the required head states, and eventually oopsing. Fix this clearing the skb head state only when processing the last skb reference.
