[PATCH] bluetooth: Fix calling many times Audio.GetProperties for the same device

[luiz.dentz@xxxxxxxxx (Luiz Augusto von Dentz)]

From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>

Audio.GetProperties is been called for as many times as there are UUIDs
instead of just once when the UUIDs are discovered.
