sr: implement sr_check_events()
Replace sr_media_change() with sr_check_events(). It normally only uses GET_EVENT_STATUS_NOTIFICATION to check both media change and eject request. If @clearing includes DISK_EVENT_MEDIA_CHANGE, it issues TUR and compares whether media presence has changed. The SCSI specific media change uevent is kept for compatibility. sr_media_change() was doing both media change check and revalidation. The revalidation part is split into sr_block_revalidate_disk().
