iommu/vt-d: Remove real DMA lookup in find_domain
commit bba9cc2cf82840bd3c9b3f4f7edac2dc8329c241 upstream.
By removing the real DMA indirection in find_domain(), we can allow
sub-devices of a real DMA device to have their own valid
device_domain_info. The dmar lookup and context entry removal paths have
been fixed to account for sub-devices.
Fixes: 2b0140c69637 ("iommu/vt-d: Use pci_real_dma_dev() for mapping")
