[RFCv2 05/17] bluetooth: Implement Handsfree Audio Agent Release()

[jprvita@xxxxxxxxx (jprvita@xxxxxxxxx)]

From: Jo?o Paulo Rechi Vita <jprvita@xxxxxxxxxxxxx>

This method is used to revoke the agent registration with the manager.
It can only be called by the manager that the agent has previously
registered with, it will be ignored if called by any other process.
