Bluetooth: Add timer to force power off
If some of the cleanup commands caused by mgmt_set_powered(off) never complete we should still force the adapter to be powered down. This is rather easy to do since hdev->power_off is already a delayed work struct. This patch schedules this delayed work if at least one HCI command was sent by the cleanup procedure.
