[PATCH 1/2] vfio/ap: Don't initialize HOST_IOMMU_DEVICE with mdev

[Zhenzhong Duan]

mdevs aren't "physical" devices and when asking for backing IOMMU info,
it fails the entire provisioning of the guest. Fix that by setting
vbasedev->mdev true so skipping HostIOMMUDevice initialization in the
presence of mdevs.

Fixes: 930589520128 ("vfio/iommufd: Implement HostIOMMUDeviceClass::realize() 
handler")
