instead of data technology (CDMA's SS is correct.)

telephony: disable the use of SMS_EXPECT_MORE by default (2/2)

CodeAurora added the use of the RIL_REQUEST_SEND_SMS_EXPECT_MORE API
which is not supported by every RIL. Disabled it by default to reflect
AOSP behavior and added a flag to enable it.

Revert "Fix for data and roaming icons"

This reverts commit e79e4d548e4b34ad1888eb90b4b165345877078d.
This patch appears to have other dependencies, and the data/voice
roaming distinction is causing lack of GSM to be intepreted
as roaming in LTE+CDMA models.
