blkfront: Fix blkfront backend switch race (bdev release)
We cannot read backend state within bdev operations, because it risks
grabbing the state change before xenbus gets to do it.
Fixed by tracking deferral with a frontend switch to Closing. State
exposure isn't strictly necessary, but the backends won't mind.
For a 'clean' deferral this seems actually a more decent protocol than
raising errors.
