USB: xHCI: Add pointer to udev in struct xhci_virt_device
Add a pointer to udev in struct xhci_virt_device. When allocate a new virt_device, make the pointer point to the corresponding udev. Modify xhci_check_args(), check if virt_dev->udev matches the target udev, to make sure command is issued to the right device.
