blkfront: Clean up vbd release
* Current blkfront_closing is rather a xlvbd_release_gendisk.
Renamed in preparation of later patches (need the name again).
* Removed the misleading comment -- this only applied to the backend
switch handler, and the queue is already flushed btw.
* Break out the xenbus call, callers know better when to switch
frontend state.
