mm/damon/core: remove start, end check in damon_set_region_system_rams()

Browse Source 
damon_set_region_system_rams() validates user inputs to avoid creating a
negative size region.  But DAMON core avoids zero size, too.  The check is
incomplete.  The complete check is done inside damon_set_regions(), which
is eventually called from damon_set_region_system_rams_default().  Drop
the incomplete and unnecessary check.
