This reverts commit 55752949. Commit 55752949 ("iommu/vt-d: Avoid duplicated pci dma alias consideration") aimed to address a NULL pointer deference issue happened when a thunderbolt device driver returned unexpectedly. Unfortunately, this change breaks a previous pci quirk added by commit cc346a47 ("PCI: Add function 1 DMA alias quirk for Marvell devices"), as the result, devices like Marvell 88SE9128 SATA controller doesn't work anymore. We will continue to try to find the real culprit mentioned in 55752949, but for now we should revert it to fix current breakage.
