[PATCH 10/12] mm/damon/reclaim: remove unnecessary code for online tuning

[SeongJae Park <sj@kernel.org>]

DAMON_RECLAIM contains code for handling of online DAMON parameters
update edge cases.  It is no more necessary since damon_commit_ctx()
takes care of the cases.  Remove the unnecessary code.
