[PATCH] mm/damon: simplify scheme create in damon_lru_sort_apply_parameters

From: Xin Hao
Date: Sat Sep 10 2022 - 12:55:59 EST


In damon_lru_sort_apply_parameters(), we can use damon_set_schemes() to
replace the way of creating the first 'scheme' in original code, this
makes the code look cleaner.
