node_device: udev: Use base 16 for product/vendor

udev doesn't prefix USB product/vendor info with '0x', so the
strtol conversions were wrong for the product field (vendor already
set the correct base). Make the change for PCI product/vendor as
well to be safe.

This fixes USB device assignment via virt-manager.
