Bug description:
  [Impact]

  ModemManager disconnects from CDMA modem after 30 sec failing to check
  signal status due to incorrect error handling

  [Test case]

  connect to a cdma device without an extra AT channel (Eg. Samsung
  brightside phone) and modemmanager will terminate the connection

  [Regression potential]

  The patch is tiny, fixing an obvious overlook, and it only affects
  CDMA broadband modems, so the risk of a regression is very low.

  [Original description]

  ModemManager disconnects after ~30 sec

  caused by a typo in 1.8
