iommu/vt-d: Avoid caching stale domain_device_info and fix memory leak

Browse source

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.
