Subject: [PATCH v4 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.
