Subject: [PATCH v2 1/7] Bluetooth: Translate additional address type correctly

From: Marcel Holtmann <[email protected]>

When using controller based address resolution, then the new address
types 0x02 and 0x03 are used. These types need to be converted back into
either public address or random address types.
