[BlueZ PATCH v4 7/8] adv_monitor: Fix return type of RegisterMonitor() method

[Miao-chen Chou <mcchou@chromium.org>]

This modifies the D-Bus call return type to be asynchronous for
RegisterMonitor() method call.

The following test was performed:
- Enter bluetoothctl, exit the console and re-enter the console without
AlreadyExist error for RegisterMonitor() upon bring-up of the console.
