[PATCH] Bluetooth: Skip the shutdown routine if the interface is not up

[Gabriele Mazzotta]

Most likely, the shutdown routine requires the interface to be up.
This is the case for BTUSB_INTEL: the routine tries to send a command
to the interface, but since this one is down, it fails and exits once
HCI_INIT_TIMEOUT has expired.
