mm: add pfn_swap_entry_folio()
Patch series "mm: convert mm counter to take a folio", v3.
Make sure all mm_counter() and mm_counter_file() callers have a folio,
then convert mm counter functions to take a folio, which saves some
compound_head() calls.
This patch (of 10):
Thanks to the compound_head() hidden inside PageLocked(), this saves a
call to compound_head() over calling page_folio(pfn_swap_entry_to_page())
