[SCSI] sd: implement sd_check_events()
Replace sd_media_change() with sd_check_events().
* Move media removed logic into set_media_not_present() and
media_not_present() and set sdev->changed iff an existing media is
removed or the device indicates UNIT_ATTENTION.
* Make sd_check_events() sets sdev->changed if previously missing
media becomes present.
* Event is reported only if sdev->changed is set.
This makes media presence event reported if scsi_disk->media_present
actually changed or the device indicated UNIT_ATTENTION. For backward
compatibility, SDEV_EVT_MEDIA_CHANGE is generated each time
sd_check_events() detects media change event.
