[PATCH RFC 15/32] mm/gup: use new helpers for marking folios as referenced

[Kairui Song via B4 Relay]

From: Kairui Song <kasong@xxxxxxxxxxx>

Marking the folio as referenced in gup fast was first introduced by commit
8ee53820edfd ("thp: mmu_notifier_test_young"). Then later refractored
but still basically the samething in commit e93480537fd7 ("mm/gup: Mark all
pages PageReferenced in generic get_user_pages_fast()"). Some implementation
may changed over days by the goal is the same: provide hotness info for better
memory management.

We have made all users that cares about a folio's hotness info to the
new helper, so convert this updater too.

NOTE: it would be better to convert to folio_mark_referenced later.
