The older trees don't need this one. The callers in 7.2, 6.18 and 6.12
already reject a zero target_value (7.2 also has 06befa61c427
("mm/damon/lru_sort: error out for >10000 active_mem_bp") and a16fd3ad9d89
("samples/damon/mtier: error out for zero quota goal target values")), the
commit has no Fixes: or Cc: stable, and it is patch 1/3 of a series whose
patches 2 and 3 remove those caller-side checks.
