Rémi Denis-Courmont f556a352fd phonet: take correct lock to peek at the RX queue 
[ Upstream commit 3b2d9bc4d4 ]

The receive queue is protected by its embedded spin-lock, not the
socket lock, so we need the former lock here (and only that one).

Fixes: 107d0d9b8d ("Phonet: Phonet datagram transport protocol")
