This fixes a potential issue with mdev that fails to initialize
HOST_IOMMU_DEVICE.
Reason is mdev isn't physical device and doesn't support IOMMU_GET_HW_INFO.
I thought ap/ccw are all mdev type and need a fix.
This series depends on a patch from Joao which fixes the same for vfio-pci.
See https://lists.gnu.org/archive/html/qemu-devel/2024-07/msg04612.html
Not tested due to no ap/ccw environment. But build test pass.
Thanks
