[PATCH v2 1/2] mm/vmstat: remove unused folio stat helpers

[Shivank Garg]

__zone_stat_add_folio(), __zone_stat_sub_folio(), zone_stat_add_folio(),
__node_stat_add_folio() and __node_stat_sub_folio() have had no callers
since they were added in commit a53e17e4e97b ("mm/vmstat: Add functions
to account folio statistics"). The last zone_stat_sub_folio() user was
removed in commit f1ee018baee9 ("mm: use __page_cache_release() in
folios_put()").
