This helps us to build a device-based virq report function: +void iommufd_device_report_virq(struct device *dev, unsigned int data_type,

I built a link from device to viommu reusing Baolu's work: struct device -> struct iommu_group -> struct iommu_attach_handle -> struct iommufd_attach_handle -> struct iommufd_device (idev) -> struct iommufd_vdev_id (idev->vdev_id)
That makes sense, the vdev id would be 1:1 with the struct device, and the iommufd_device is also supposed to be 1:1 with the struct device.
