Subject: [PATCH] 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.
