DCTracker: HACK Fix eHRPD/LTE data connection.

* UICC controller is suppose to send a event that says uicc updated
  We are experiencing a race condition when UICC is init before the
  radio start which cause the sim is not ready response from radio.
* This forces data when we have cdma voice connection.
