Remove apntype ims on Vzw legacy CDMA networks

Vzw doesn't support IMS over legacy CMDA networks.
Keeping the ims type under 1x causes QC CNE module to use
existing default 1x data in a 1x and wifi only scenario.
After this change the IMS data call will be setup over
wifi instead of using the existing 1x data call.
