sctp: sctp should change socket state when shutdown is received
Now sctp doesn't change socket state upon shutdown reception. It changes just the assoc state, even though it's a TCP-style socket. For some cases, if we really need to check sk->sk_state, it's necessary to fix this issue, at least when we use ss or netstat to dump, we can get a more exact information. As an improvement, we will change sk->sk_state when we change asoc->state to SHUTDOWN_RECEIVED, and also do it in sctp_shutdown to keep consistent with sctp_close.
