af_unix: Fix data race around sk->sk_err.
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 cc04410af7de ("af_unix:
annotate lockless accesses to sk->sk_err").
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
