mm/damon/lru_sort: consider age for quota prioritization

Browse Source 
DAMON_LRU_SORT is doing under-quota access pattern based regions
prioritization using only access frequency.  Age of regions is another
useful information for distinguishing hot and cold regions.  Use it for
prioritization, too.
