mm/damon/paddr: support only damos->ops_filters 

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.
