mm/damon/core.c: avoid unintentional filtering out of schemes

Browse source 
commit 13b2a4b22e98ff80b888a160a2acd92d81b05925 upstream.

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'.
