[v2,3/3] mm/swap: Convert deactivate_page() to folio_deactivate()

Commit Message

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.

Using 'extern' on function prototypes is now unfashionable; you can drop
it if you respin this patch.
