iommufd/selftest: Require vdev_id when attaching to a nested domain
When attaching a device to a vIOMMU-based nested domain, vdev_id must be
present. Add a piece of code hard-requesting it, preparing for a vEVENTQ
support in the following patch. Then, update the TEST_F.
A HWPT-based nested domain will return a NULL new_viommu, thus no such a
vDEVICE requirement.
