3773696 - AIF - /AIF/IFMON mass cancellation blocks TRFC processing on destination none

• When performing mass cancellation of erroneous messages in transaction /AIF/IFMON, tRFC entries for unrelated processes queue in destination NONE and are not processed.
• Newly arriving RFC calls accumulate behind the long-running cancellation task.
• Transaction SM58 shows queued/locked tRFC calls in destination NONE.

• when use mass cancellation heavily, which uses the NONE destination as an RFC call from:
  /AIF/CL_APPL_ENGINE_XML_NRT /AIF/IF_APPLICATION_ENGINE~MASS_CANCEL

  •     CALL FUNCTION '/AIF/NRT_MASS_CANCEL'
          IN BACKGROUND TASK
          EXPORTING
            is_if_msgs = is_if_msgs.
        COMMIT WORK.
        RETURN.

  So if too many messages was cancel, this FM keeps the NONE destination queue hanging.
