mm/damon: improve damon_new_region strategy
Kdamond is implemented as a periodical split-merge pattern, which will
create and destroy regions possibly at high frequency (hundreds or even
thousands of per sec), depending on the number of regions and aggregation
period. In that case, kmalloc and kfree could bring speed and space
overheads, which can be improved by using a private kmem cache.
