[PATCH mm-unstable] mm/damon: document get_score_arg field of struct damos_quota

[SeongJae Park]

Commit 99b36eab9c05 ("mm/damon/core: implement goal-oriented
feedback-driven quota auto-tuning") on mm-unstable missed documenting
'get_score_arg' field of 'struct damos_quota' on the kernel-doc comment.
Fix it.
