IMS: Fix phone app crash at setOutgoingCallerIdDisplay().

Phone process crash due to duplicate callback received at
GsmPhone when launch additional call settings and click on
Caller ID->Hide number.
Correct logic to receive messge EVENT_SET_CLIR_COMPLETE by
the requested phone (GsmPhone or ImsPhone), not by both.
