Still get & pass revision to update GC safe point interface. p.s. In this scenario, revision will be `-1.

@pingyu What revision is returned from GetGCMinServiceSafePointByServiceGroup interface in this scenario? Could gc-worker pass the returned revision to UpdateGCSafePointByServiceGroup or need hard code to -1?
