iommu/vt-d: Avoid caching stale domain_device_info and fix memory leak
Function device_notifier() in intel-iommu.c fails to remove device_domain_info data structures for PCI devices if they are associated with si_domain because iommu_no_mapping() returns true for those PCI devices. This will cause memory leak and caching of stale information in domain->devices list. So fix the issue by not calling iommu_no_mapping() and skipping check of iommu_pass_through.
