Kuniyuki Iwashima 3d25de6486 af_unix: Annotate data-race of sk->sk_state in unix_stream_connect().
[ Upstream commit a9bf9c7dc6a5899c01cb8f6e773a66315a5cd4b7 ]

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.
