mm/damon/lru_sort: adjust local variable to dynamic allocation

When KASAN is enabled and built with clang:
    mm/damon/lru_sort.c:199:12: error: stack frame size (2328) exceeds
limit (2048) in 'damon_lru_sort_apply_parameters' [-Werror,-Wframe-larger-than]
    static int damon_lru_sort_apply_parameters(void)
               ^
    1 error generated.

This is because damon_lru_sort_quota contains a large array, and
assigning this variable to a local variable causes a large amount of
stack space to be occupied.

So adjust local variable to dynamic allocation.
