There is no VFIO_MAP_DMA error when hotplug 2 E810 PFs into a VM which
has a virtio-iommu device.
In addition, 21 regression tests of Tier1 level were run and all got PASS.

After applying this patch, the Q35 + OVMF L2 VM with a igbvf will not
throw the error like:
[1]VFIO_MAP_DMA failed: Invalid argument.
[2]vfio_dma_map(0x560a1a64e3b0, 0x38304000, 0x4000,
0x7fcfc4053000) = -22 (Invalid argument)

:b1:00.2: VFIO migration is not supported with postcopy migration"
