Please, don't do that, don't put function calls in DBUG_RETURN.
This will result in dbug traces like

   > select_insert::send_eof
   < select_insert::send_eof
   > select_insert::prepare_eof
   < select_insert::prepare_eof
   > select_insert::send_ok_packet
   < select_insert::send_ok_packet

while the correct trace should've be

   > select_insert::send_eof
   | > select_insert::prepare_eof
   | < select_insert::prepare_eof
   | > select_insert::send_ok_packet
   | < select_insert::send_ok_packet
   < select_insert::send_eof

So, either write like

  bool res= prepare_eof() || send_ok_packet();
  DBUG_RETURN(res);

or fix DBUG_RETURN() macro. Whatever you prefer :)

Otherwise the patch is ok.
