Eric Auger 3745768918 virtio-iommu: Remove probe_done ... Now we have switched to PCIIOMMUOps to convey host IOMMU information, the host reserved regions are transmitted when the PCIe topology is built. This happens way before the virtio-iommu driver calls the probe request. So let's remove the probe_done flag that allowed to check the probe was not done before the IOMMU MR got enabled. Besides this probe_done flag had a flaw wrt migration since it was not saved/restored. The only case at risk is if 2 devices were plugged to a PCIe to PCI bridge and thus aliased. First of all we discovered in the past this case was not properly supported for neither SMMU nor virtio-iommu on guest kernel side: see [RFC] virtio-iommu: Take into account possible aliasing in virtio_iommu_mr() https://lore.kernel.org/all/20230116124709.793084-1-eric.auger@redhat.com/ If this were supported by the guest kernel, it is unclear what the call sequence would be from a virtio-iommu driver point of view.
