iommu/vt-d: Reduce extra first level entry in iommu->domains
In commit <8bf478163e69> ("iommu/vt-d: Split up iommu->domains array"), it
it splits iommu->domains in two levels. Each first level contains 256
entries of second level. In case of the ndomains is exact a multiple of
256, it would have one more extra first level entry for current
implementation.
This patch refines this calculation to reduce the extra first level entry.
