IB/cm: Send no match if a SIDR REQ does not match a listen

If a SIDR REQ does not match a listen, we should reply with status
value 1 (service ID not supported), rather than dropping through to
the default case of status 2 (rejected by service provider).

Doing this also fixes a bug where the cm_id_priv is removed from the
remote_sidr_table twice.
