mm/damon/core: put ops-handled filters to damos->ops_filters

Browse Source 
damos->ops_filters has introduced to be used for all operations layer
handled filters.  But DAMON kernel API callers can put any type of DAMOS
filters to any of damos->filters and damos->ops_filters.  DAMON user-space
ABI users have no way to use ->ops_filters at all.  Update
damos_add_filter(), which should be used by API callers to install DAMOS
filters, to add filters to ->filters and ->ops_filters depending on their
handling layer.  The change forces both API callers and ABI users to use
proper lists since ABI users use the API internally.
