Fix R icon shows for a short while

In architecture 1x + LTE, Phone may switch to GSM as per carrier's
requirement, but at that time, Telephony has got LTE RAT, but just
1x signal strenght is there, so that UI has a little bit change to
show R icon as per CDMA.

To fix it, initialize mNewSS as out of service.
