telephony: SignalStrengh: Don't calculate a LTE snr if the srq is invalid
If the previous values are invalid and signal quality is -1, chances are there's
no LTE signal at all, so don't calculate the SNR and mark it invalid as well.
This fixes the strength indicator in GSM devices where it was being skewed
by the ghost LTE value
