sr: use bdev_check_media_change

Switch to use bdev_check_media_change instead of check_disk_change and
call sr_block_revalidate_disk manually.  Also add an explicit call to
sr_block_revalidate_disk just before disk_add() to ensure we always
read check for a ready unit and read the TOC and then stop wiring up
->revalidate_disk.
