Subject[PATCH] sr: Fix get the error media event code
Date
Eject the specified slot or media through a mechanical switch on the Drive,
med->media_event_code is 3 not 1 in the sr_get_events().

If disk_flush_events() and sr_block_open() are called,
clearing is 1 or 3 in the sr_check_events(),then it report
DISK_EVENT_MEDIA_CHANGE not DISK_EVENT_EJECT_REQUEST.

If disk_flush_events() and sr_block_open() aren't called,
clearing is 0 in the sr_check_events(),then it doesn't
report any event.
