af_unix: Use skb_queue_len_lockless() in sk_diag_show_rqlen().
[ Upstream commit 5d915e584d8408211d4567c22685aae8820bfc55 ]
We can dump the socket queue length via UNIX_DIAG by specifying
UDIAG_SHOW_RQLEN.
If sk->sk_state is TCP_LISTEN, we return the recv queue length,
but here we do not hold recvq lock.
Let's use skb_queue_len_lockless() in sk_diag_show_rqlen().
Fixes: c9da99e6475f ("unix_diag: Fixup RQLEN extension report")
