Jan Beulich e73ab4e84b VT-d: refuse to use IOMMU with reserved CAP.ND value ...

The field taking the value 7 (resulting in 18-bit DIDs when using the
calculation in cap_ndoms(), when the DID fields are only 16 bits wide)
is reserved. Instead of misbehaving in case we would encounter such an
IOMMU, refuse to use it.
