QualcommSharedRIL:  Bypass CDMA subscription in handler switch to avoid crashing of telephony stack.

HTC EVO LTE gets subscription from both UICC and NV. The problem here is NV isn't ready
yet causing cdma subscription to return -1 and cause the stack to crash. fix is to bypass
CDMA subscription here and get UMTS subscription. Then get CDMA subscription later after NV is ready.

Use ro.telephony.ril.v3=skipCdmaSubcription to bypass CDMA subscription in this switch.
