rbd: Set r variable so it can be returned should an error occur

Browse Source 
This was reported in bug #1298024 where r would be filled with the
return code of rbd_open().

Should rbd_snap_unprotect() fail for any reason the virReportSystemError
call would return 'Success' since rbd_open() succeeded.
