Bluetooth: Do not trigger background scanning when HCI_AUTO_OFF is set
When a new controller is initialized, but not powered from userspace at the moment, the HCI_AUTO_OFF flag is still set. During this period, userspace might program device for auto-connection, but never power on the controller. In this case do not try to start background scanning and leave it for later to be started.
