sctp: set sk_state back to CLOSED if autobind fails in sctp_listen_start

In the Linux kernel, the following vulnerability has been resolved:

sctp: set sk_state back to CLOSED if autobind fails in sctp_listen_start

In sctp_listen_start() invoked by sctp_inet_listen(), it should set the
sk_state back to CLOSED if sctp_autobind() fails due to whatever reason.

Otherwise, next time when calling sctp_inet_listen(), if sctp_sk(sk)->reuse
is already set via setsockopt(SCTP_REUSE_PORT), sctp_sk(sk)->bind_hash will
be dereferenced as sk_state is LISTENING, which causes a crash as bind_hash
is NULL.
