rbd: get rid of some version parameters
Several functions in rbd have parameters meant to allow the version of an object to be passed in or out. The purpose of those was to allow the version of a header object to be maintained, but we no longer do that. As a result, these parameters are never actually needed or used, so get rid of them.
