Subject: [PATCH] iommu/vt-d: Match segment number when searching for dev_iotlb
 capable devices

For virtual machine and static identity domains, there may be devices
from different PCI segments associated with the same domain.
So function iommu_support_dev_iotlb() should also match PCI segment
number (iommu unit) when searching for dev_iotlb capable devices.
