In some initialization conditions (having never ran stack.sh) the result of unstack.sh is dependent on if the user had previously installed lvm2 or disabled the cinder service. This change makes all results the same with a bit of LBYL. There's also a drive-by to put a comment back where it belongs after being accidentally moved in the related change.
