Bug #12956584 - MYSQLTEST: --ENABLE_X OR --DISABLE_X APPLYING ONLY TO NEXT COMMAND/STMT

  Followup fixes for --ps-protocol:
  1) Incorrectly set ps_protocol variable instead of ps_protocol_enabled
  2) disable_result_log was tested after calling handle_no_error()
        which would revert a temporary setting.
