Bluetooth: bpa10x: Free private driver data on usb shutdown
Instead of waiting for the hci-device to be destroyed we now free the
private driver data on driver shutdown right away. We call
hci_unregister_dev() on driver shutdown, that means, the hci-core will
never ever call our callbacks again except the destruct callback. It
also does not access hdev->driver_data so there is no reason to keep
that alive. We simply set the destruct cb to NULL to avoid getting
called again.
