For sending request messages to data plane threads, the
caller invokes pipeline_msg_send_recv() function which never
returns null response. Thus, removed redundant check on
the returned response.

Coverity Issues: 357750, 357740, 357749, 357758, 357702, 357736,
357679, 357791, 357738, 357778, 357716, 357705, 357776, 357753,
357729, 357735
