Subject: iommu/amd: Correct the wrong setting of alias DTE in do_attach

From: Baoquan He <redacted>

commit 9b1a12d29109234d2b9718d04d4d404b7da4e794 upstream.

In below commit alias DTE is set when its peripheral is
setting DTE. However there's a code bug here to wrongly
set the alias DTE, correct it in this patch.
