xhci: Add an assertion to check for virt_dev=0 bug. During a "plug-unplug" stress test on an NEC xHCI card, a null pointer dereference was observed. xhci_address_device() dereferenced a null virt_dev (possibly an erroneous udev->slot_id?); this patch adds a WARN_ON & message to aid debug if it can be recreated.
