Kuniyuki Iwashima 776fcc45e3 af_unix: Annotate data-races around sk->sk_state in sendmsg() and recvmsg().
[ Upstream commit 8a34d4e8d9742a24f74998f45a6a98edd923319b ]

The following functions read sk->sk_state locklessly and proceed only if
the state is TCP_ESTABLISHED.

  * unix_stream_sendmsg
  * unix_stream_read_generic
  * unix_seqpacket_sendmsg
  * unix_seqpacket_recvmsg

Let's use READ_ONCE() there.

Fixes: a05d2ad1c1f3 ("af_unix: Only allow recv on connected seqpacket sockets.")
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
