Alejandro Jimenez c5b0320bbf iommu/amd: Preserve default DTE fields when updating Host Page Table Root ... When updating the page table root field on the DTE, avoid overwriting any bits that are already set. The earlier call to make_clear_dte() writes default values that all DTEs must have set (currently DTE[V]), and those must be preserved. Currently this doesn't cause problems since the page table root update is the first field that is set after make_clear_dte() is called, and DTE_FLAG_V is set again later along with the permission bits (IR/IW). Remove this redundant assignment too.
