iommu/vt-d: Remove comment for def_domain_type

Browse Source 
The comment for def_domain_type is outdated. Part of it is irrelevant.
Furthermore, it could just be deleted since the iommu_ops::def_domain_type
callback is properly documented in iommu.h, so individual implementations
shouldn't need to repeat that. Remove it to avoid confusion.
