iommu/amd: Update Alias-DTE in update_device_table()

commit 3254de6bf74fe94c197c9f819fe62a3a3c36f073 upstream.

Not doing so might cause IO-Page-Faults when a device uses
an alias request-id and the alias-dte is left in a lower
page-mode which does not cover the address allocated from
the iova-allocator.
