Due to some oversight, the SCSI capability for reporting media change
notifications was never actually translated into setting the appropriate
GENHD_FL_MEDIA_CHANGE_NOTIFY flag. HAL uses this flag to detect whether the
block device supports change notifications and so it never actually got
detected. Set the flag when appropriate in sd and sr.

Gaah, am I disappointed in finding this one. Apparently people went to the
trouble of adding ATAPI AN support, and adding the appropriate flags to indicate
to userspace that it was supported, but nobody ever tested to make sure that
the support worked all the way through to actually make HAL stop polling
optical drives that support AN, which to my dismay, it doesn't. In fact even
with this patch it still doesn't seem to, but that's presumably some HAL bug.
HAL does now report that storage.removable.support_async_notification = true,
however.
