iommu/vt-d: Save the right domain ID used by hardware
The driver sets a default domain id (FLPT_DEFAULT_DID) in the
first level only pasid entry, but saves a different domain id
in @sdev->did. The value saved in @sdev->did will be used to
invalidate the translation caches. Hence, the driver might
result in invalidating the caches with a wrong domain id.
