Joao Martins 83a4d596a9 vfio/{iommufd, container}: Invoke HostIOMMUDevice::realize() during attach_device() ... Move the HostIOMMUDevice::realize() to be invoked during the attach of the device before we allocate IOMMUFD hardware pagetable objects (HWPT). This allows the use of the hw_caps obtained by IOMMU_GET_HW_INFO that essentially tell if the IOMMU behind the device supports dirty tracking. Note: The HostIOMMUDevice data from legacy backend is static and doesn't need any information from the (type1-iommu) backend to be initialized. In contrast however, the IOMMUFD HostIOMMUDevice data requires the iommufd FD to be connected and having a devid to be able to successfully GET_HW_INFO. This means vfio_device_hiod_realize() is called in different places within the backend .attach_device() implementation.
