khugepage: replace try_to_release_page() with filemap_release_folio()

[ Upstream commit 64ab3195ea077eaeedc8b382939c3dc5ca56f369 ]

Replace some calls with their folio equivalents.  This change removes 4
calls to compound_head() and is in preparation for the removal of the
try_to_release_page() wrapper.
