DAMON keeps all DAMOS filters in damos->filters.  Upcoming changes will
make it to use damos->ops_filters for all operations layer handled DAMOS
filters, though.  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.
