Fix spurious 0300_0002 error notification via HMS array path (#583)

The previous fix only filtered status codes (< 0x4000) from the
  print_error field. Firmware can also send the same false positive
  through the hms array in MQTT, which had no such filter. Apply the
  same < 0x4000 check to the HMS parser so status/phase indicators
  are skipped regardless of which MQTT field carries them.
