Bluetooth: fix invalid-bdaddr quirk for non-persistent setup

Browse Source 
Devices that lack persistent storage for the device address can indicate
this by setting the HCI_QUIRK_INVALID_BDADDR which causes the controller
to be marked as unconfigured until user space has set a valid address.

Once configured, the device address must be set on every setup for
controllers with HCI_QUIRK_NON_PERSISTENT_SETUP to avoid marking the
controller as unconfigured and requiring the address to be set again.
