Kuniyuki Iwashima 6fdc1152af af_unix: Annotate data-race of sk->sk_state in unix_accept().
[ Upstream commit 1b536948e805aab61a48c5aa5db10c9afee880bd ]

Once sk->sk_state is changed to TCP_LISTEN, it never changes.

unix_accept() takes the advantage and reads sk->sk_state without
holding unix_state_lock().

Let's use READ_ONCE() there.
