mm/damon/sysfs-schemes: avoid Wformat-security warning on damon_sysfs_access_pattern_...

When -Wformat-security is given, compiler warns as a potential security
issue on damon_sysfs_access_pattern_add_range_dir() as below:

    mm/damon/sysfs-schemes.c: In function `damon_sysfs_access_pattern_add_range_dir':
    mm/damon/sysfs-schemes.c:1503:25: warning: format not a string literal and no format arguments [-Wformat-security]
     1503 |                         &access_pattern->kobj, name);
          |                         ^

Fix it by using "%s" as the format and the name as the argument.
