iommu/amd: Control INVALIDATE_IOMMU_PAGES PDE from the gather

Now that AMD uses iommupt, it is easy to make use of the PDE bit. If
the gather has no free list then no page directory entries were
changed.

Pass GN/PDE through the invalidation call chain in a u32 flags field
that is OR'd into data[2] and set it properly from the gather.
