net: skb_free_datagram_locked() fix
Commit 4b0b72f7dd617b ( net: speedup udp receive path )
introduced a bug in skb_free_datagram_locked().
We should not skb_orphan() skb if we dont have the guarantee we are the
last skb user, this might happen with MSG_PEEK concurrent users.
To keep socket locked for the smallest period of time, we split
consume_skb() logic, inlined in skb_free_datagram_locked()
