VT-d: defer "no DRHD" check when (un)mapping devices

If devices are to be skipped anyway (which is the case in particular for
host bridges), there's no point complaining about a missing DRHD (and
hence a missing association with an IOMMU).

While there convert assignments to initializers and constify "drhd"
local variables.
