DAMON physical address space operation set implementation (paddr)
started handling both damos->filters and damos->ops_filters to avoid
breakage during the change for the ->ops_filters setup. Now the change
is done, so paddr's support of ->filters is only a waste that can safely
be dropped. Remove it.
