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.
