CdmaLte: call setDataRegState when using RilVoiceRadioTechnology for data

When using the VoiceRadioTechnology to set the DataRadioTechnology
(by using usevoicetechfordata in ro.telephony.ril.v3), the actual
data registration state needs also to be updated with the service
state depending on the VoiceRadioTechnology. Without this, no data
connection would be established.
