mm/slab: remove duplicate check in create_cache()
The WARN_ON() check in static function create_cache() is done by its only
parent __kmem_cache_create_args() before calling it.
if (... ||
WARN_ON(... ||
object_size - args->usersize < args->useroffset))
args->usersize = args->useroffset = 0;
...
s = create_cache(cache_name, object_size, args, flags);
Therefore, the WARN_ON() check in create_cache() can be safely removed.
