Mark Johnston c98bf2a45e sctp: Always check for a vanishing inpcb when processing COOKIE-ECHO
We previously did this only in the normal case where no association
exists yet.  However, it is not safe to process COOKIE-ECHO even if an
association exists, as sctp_process_cookie_existing() may dereference
the socket pointer.
