Bluetooth: hci_bcm4377: do not mark valid bd_addr as invalid
commit c17d2a7b216e168c3ba62d93482179c01b369ac7 upstream. A recent commit restored the original (and still documented) semantics for the HCI_QUIRK_USE_BDADDR_PROPERTY quirk so that the device address is considered invalid unless an address is provided by firmware. This specifically means that this flag must only be set for devices with invalid addresses, but the Broadcom BCM4377 driver has so far been setting this flag unconditionally. Fortunately the driver already checks for invalid addresses during setup and sets the HCI_QUIRK_INVALID_BDADDR flag, which can simply be replaced with HCI_QUIRK_USE_BDADDR_PROPERTY to indicate that the default address is invalid but can be overridden by firmware (long term, this should probably just always be allowed).
