Simon Arlott b8cf0e0e55 cdrom: support devices that have check_events but not media_changed ...

Commit 93aae17af1172c40c6f74b7294e93a90c3cfaa5d ("sr: implement
sr_check_events()") replaced the media_changed op with the
check_events op in drivers/scsi/sr.c

All users that check for the CDC_MEDIA_CHANGED capbility try both
the check_events op and the media_changed op, but register_cdrom()
was requiring media_changed.

This patch fixes the capability checking.

The cdrom_select_disc ioctl is also using the two operations, so
they should be required for CDC_SELECT_DISC too.
