[PATCH] Bluetooth: Set default own address type only during controller setup

[PATCH] Bluetooth: Set default own address type only during controller setup

[Marcel Holtmann]

The default own address type is currently set at every power on of
a controller. This overwrites the value set via debugfs. To avoid
this issue, set the default own address type only during controller
setup.
