policy_hal: Always call local implementation of updateCallRouting

* updateCallRouting is not a virtual function, so any calls to the local
  implementation from the superclass will call the superclass's version
  instead of correctly calling the local version.
* Override implementations of virtual functions that DO call
  updateCallRouting (setDeviceConnectionState, setPhoneState,
  setForceUse) to ensure the local version of the function is
  called.
