Docs/admin-guide/mm/damon/usage: fix and add missing DAMOS filter sysfs files on files hierarchy

DAMOS filter directory part of DAMON sysfs files hierarchy on the usage
document is wrong.  'memcg_path' file under the directory is wrongly
written as 'memcg_id'.  Also the directory has 'addr_start', 'addr_end',
and 'target_idx' files, but the list is missing those.  Fix the wrong name
and add missing files.
