This patch registers a callback function to receive Advertisement
Monitor Device Lost event.
Test performed:
- verified by logs that Monitor Device is received from the controller
and sent to the bluetoothd when the controller starts/stops monitoring
a bluetooth device.
---
Changes in v2:
- Update function name adv_monitor_tracking_callback() to
adv_monitor_device_lost_callback() as it will receive only Device Lost
event.
