setup_per_zone_pages_min(): take zone->lock instead of zone->lru_lock
commit 1125b4e3949949b44a7c80b619507c6f61d62911 upstream. This replaces zone->lru_lock in setup_per_zone_pages_min() with zone->lock. There seems to be no need for the lru_lock anymore, but there is a need for zone->lock instead, because that function may call move_freepages() via setup_zone_migrate_reserve().
