Kuniyuki Iwashima 2100bbf55e af_unix: Fix data race around sk->sk_err. ...

[ Upstream commit b192812905 ]

As with sk->sk_shutdown shown in the previous patch, sk->sk_err can be
read locklessly by unix_dgram_sendmsg().

Let's use READ_ONCE() for sk_err as well.

Note that the writer side is marked by commit cc04410af7 ("af_unix:
annotate lockless accesses to sk->sk_err").
