Docs/admin-guide/mm/damon/usage: fix wrong example of DAMOS filter matching sysfs file
The example usage of DAMOS filter sysfs files, specifically the part of
'matching' file writing for memcg type filter, is wrong. The intention is
to exclude pages of a memcg that already getting enough care from a given
scheme, but the example is setting the filter to apply the scheme to only
the pages of the memcg. Fix it.
