af_unix: Annotate data-races around sk->sk_state in UNIX_DIAG.
[ Upstream commit 0aa3be7b3e1f8f997312cc4705f8165e02806f8f ]
While dumping AF_UNIX sockets via UNIX_DIAG, sk->sk_state is read
locklessly.
Let's use READ_ONCE() there.
Note that the result could be inconsistent if the socket is dumped
during the state change. This is common for other SOCK_DIAG and
similar interfaces.
