mctp: Avoid warning if unregister notifies twice
Previously if an unregister notify handler ran twice (waiting for
netdev to be released) it would print a warning in mctp_unregister()
every subsequent time the unregister notify occured.
Instead we only need to worry about the case where a mctp_ptr is
set on an unknown device type.
