[PATCH 1/2] Bluetooth: Do not trigger background scanning when HCI_AUTO_OFF is set

[Marcel Holtmann]

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.

Both patches have been applied to bluetooth-next. Thanks.
