mm/damon/lru_sort: remove unnecessary damon_call() param validation

Browse Source 
DAMON_LRU_SORT avoids passing NULL or unstarted damon_ctx to damon_call()
with its own validation.  The validation is no longer needed, because the
DAMON core layer now handles the corner cases itself.  Remove the
unnecessary check.
