PCI: vmd: Revert 2565e5b6 ("PCI: vmd: Do not disable MSI-X remapping if interrupt remapping is enabled by IOMMU.")

Revert 2565e5b6 ("PCI: vmd: Do not disable MSI-X remapping if
interrupt remapping is enabled by IOMMU.")

The commit 2565e5b6 was added as a workaround to keep MSI-X
remapping enabled if IOMMU enables interrupt remapping. VMD would keep
running in low performance mode. There is no dependency between MSI-X
remapping by VMD and interrupt remapping by IOMMU.
