IOMMUTLBEntry.iova is returned incorrectly on one PT path (though mostly
we cannot really trigger this path, even if we do, we are mostly
disgarding this value, so it didn't break anything). Fix it by
converting the VTD_PAGE_MASK into the correct definition
VTD_PAGE_MASK_4K, then remove VTD_PAGE_MASK.
