Prevents dereferencing an invalid struct usb_interface pointer. Always delete entry from device list whether or not the rest of the device state cleanup is postponed. The device list uses desc->intf as key, and wdm_open will dereference this key while searching for a matching device. A device should not appear in the list unless probe() has succeeded and disconnect() has not finished.
