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.
