tcp: fix access to sk->sk_state in tcp_poll()
avoid direct access to sk->sk_state when tcp_poll() is called on a socket using active TCP fastopen with deferred connect. Use local variable 'state', which stores the result of sk_state_load(), like it was done in commit 00fd38d9 ("tcp: ensure proper barriers in lockless contexts").
