In this patch, we replace one argument of function
finish_op_on_target, "packet(op) type", with "has_response_data".
Since finish_op_on_target does not care what specific
packet(op) type it is processing on, but only cares
about if the current op has response data (like GET/GACC),
changing the argument in this way can simplify the
code by avoiding acquiring packet(op) type everytime
before calling finish_op_on_target.
