Commit 1b00c16bdf ("AMD/IOMMU: pre-fill all DTEs right after table
allocation") moved ourselves into a more secure default state, but
didn't take sufficient care to also undo the effects when handing a
previously disabled device back to a(nother) domain. Put the fields
that may have been changed elsewhere back to their intended values
(some fields amd_iommu_disable_domain_device() touches don't
currently get written anywhere else, and hence don't need modifying
here).
