The code already had the is_swap_pte() check in it, so this is not changing
anything, it's just avoiding confusion.

Well, in hpage_collapse_scan_pmd(), in __collapse_huge_page_isolate() no :)

And then it's called SCAN_PTE_NON_PRESENT and it all starts being a mess TBH.

But as raised offline, I don't have the time+energy for that today, so I don't care enough.
