mm/damon/core: fix damos_commit_filter not changing allow

commit b3dee902b6c26b7d8031a4df19753e27dcfcba01 upstream.

Current damos_commit_filter() does not persist the `allow' value of the
filter.  As a result, changing the `allow' value of a filter and
committing doesn't change the `allow' value.

Add the missing `allow' value update, so committing the filter
persistently changes the `allow' value well.
