Subject: [PATCH v3 4/4] mm/swap: Convert deactivate_page() to folio_deactivate()

Deactivate_page() has already been converted to use folios, this change
converts it to take in a folio argument instead of calling page_folio().
It also renames the function folio_deactivate() to be more consistent
with other folio functions.

(for future series like this, it's slightly fewer changes to introduce
folio_deactivate() first and change deactivate_page() to be a wrapper.
Then patches 2 & 3 in this series can just be converted straight to
folio_deactivate() instead of being changed twice. wouldn't ask
you to redo the patch series at this point, but next time ...)
