Remove duplicate call disconnect codes.

The Android code base defines call disconnect codes in three places:
 - android.telephony.DisconnectCause
 - android.internal.telephony.Connection.DisconnectCause
 - com.android.services.telephony.common.Call.DisconnectCause

This CL consolidates the code to use the integer codes from
android.telephony.DisconnectCause everywhere.
