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.
