Revert "SamsungExynos3RIL: Handle UNSOL_DATA_CALL_LIST_CHANGED."

RIL_UNSOL_DATA_CALL_LIST_CHANGED is already being handled properly
using responseDataCallList in the parent RIL class. Handling it (improperly)
here using responseVoid breaks data connectivity on galaxysmtd in
some circumstances.

This reverts commit d11286f7e96aa4d477ee869b81aef33d91f1b70d.
