[PATCH v4 3/4] mm/damon: Convert damon_pa_mark_accessed_or_deactivate() to use folios

[Vishal Moola (Oracle)]

This change replaces 2 calls to compound_head() from put_page() and 1 call
from mark_page_accessed() with one from page_folio(). This is in
preparation for the conversion of deactivate_page() to
folio_deactivate().
