[SCTP]: Set ports in every address returned by sctp_getladdrs() 



Thomas Dreibholz has reported that port numbers are not filled
in the results of sctp_getladdrs() when the socket was bound
to an ephemeral port.  This is only true, if the address was
not specified either.  So, fill in the port number correctly.
