DAMON keeps all DAMOS filters in damos->filters. No filter is saved in damos->ops_filters, but upcoming changes will make it to use damos->ops_filters to have all operations layer handled DAMOS filters. DAMON physical address space operations set implementation (paddr) is not ready for the changes, since it handles only damos->filters. To avoid any breakage during the upcoming changes, make paddr to handle both lists. After the change is made, ->filters support on paddr can be safely removed.
