[PATCH mm-unstable 1/2] mm/damon: add kernel-doc comment for damon_operations->cleanup_target

[SeongJae Park <sj@kernel.org>]

Commit 769bd386e490 ("mm/damon/core: add cleanup_target() ops callback")
on mm-unstable added cleanup_target field to damon_operations, but
forgot adding the kernel-doc description.  This causes a build warning.
Fix it by adding the description.
