mm/damon/core: fix potential memory leak by cleaning ops_filter in damon_destroy_scheme
commit 7071537159be845a5c4ed5fb7d3db25aa4bd04a3 upstream.
Currently, damon_destroy_scheme() only cleans up the filter list but
leaves ops_filter untouched, which could lead to memory leaks when a
scheme is destroyed.
This patch ensures both filter and ops_filter are properly freed in
damon_destroy_scheme(), preventing potential memory leaks.
