loc_api_v02: Initialize the QMI notifier before looking for service

Browse source 
Looking for a service results in opening and closing the IPC Router
socket. This in turn involves IPC Router to trigger loading & unloading
the modem. Sometimes this causes the race condition between modem unload
and modem coming out of reset.
