Rémi Denis-Courmont 0a9f558c72 phonet/pep: fix racy skb_queue_empty() use
[ Upstream commit 7d2a894d7f487dcb894df023e9d3014cf5b93fe5 ]

The receive queues are protected by their respective spin-lock, not
the socket lock. This could lead to skb_peek() unexpectedly
returning NULL or a pointer to an already dequeued socket buffer.
