Matthew Booth cedf281c73 Make close on cryptsetup volumes idempotent
When recovering from the failure of a compute host, Nova can call
close on an encryptor whose state Nova can't be certain of, but which
hasn't been created. This change makes the close operation idempotent,
which allows recovery to be more robust.
