Kuniyuki Iwashima a9bf9c7dc6 af_unix: Annotate data-race of sk->sk_state in unix_stream_connect().
As small optimisation, unix_stream_connect() prefetches the client's
sk->sk_state without unix_state_lock() and checks if it's TCP_CLOSE.

Later, sk->sk_state is checked again under unix_state_lock().

Let's use READ_ONCE() for the first check and TCP_CLOSE directly for
the second check.
