mm/damon: rename damos->filters to damos->core_filters

DAMOS filters that are handled by the ops layer are linked to
damos->ops_filters.  Owing to the ops_ prefix on the name, it is easy to
understand it is for ops layer handled filters.  The other types of
filters, which are handled by the core layer, are linked to
damos->filters.  Because of the name, it is easy to confuse the list is
there for not only core layer handled ones but all filters.  Avoid such
confusions by renaming the field to core_filters.
