Subject: mm/damon/lru_sort: use damon_initialized()

DAMON_LRU_SORT is assuming DAMON is ready to use in module_init time, and
uses its own hack to see if it is the time.  Use damon_initialized(),
which is a way for seeing if DAMON is ready to be used that is more
reliable and better to maintain instead of the hack.
