That hunk belongs logically into the previous patch which removes
sme_active().

I was trying to keep the sev_active() changes separate... so even though
it's an SME thing, I kept it here. But I can move it to the previous
patch, it just might look strange.

Oh I meant only the comment because it is a SME-related change. But not
too important so whatever.
