vio: create routines for inc,dec vio dring indexes Both sunvdc and sunvnet implemented distinct functionality for incrementing and decrementing dring indexes. Create common functions for use by both from the sunvnet versions, which were chosen since they will still work correctly in case a non power of two ring size is used.
