There is a check in the clone API call that prohibits cloning when a bind or device mountpoint is present. Converting to a template also will fail when such a mountpoint is present. In particular, that failure will also trigger at the end of a restore operation, because restore will also try to convert to a template again. Add a safeguard so that users won't get into the problematic situation in the first place.
