Subject: mm/damon/core.c: avoid unintentional filtering out of schemes
Date: Fri, 10 Nov 2023 14:37:09 +0900

The function '__damos_filter_out()' causes DAMON to always filter out
schemes whose filter type is anon or memcg if its matching value is set
to false.

This commit addresses the issue by ensuring that '__damos_filter_out()'
no longer applies to filters whose type is 'anon' or 'memcg'.
