mm: page_alloc: do not cache reclaim distances
pgdat->reclaim_nodes tracks if a remote node is allowed to be reclaimed
by zone_reclaim due to its distance. As it is expected that
zone_reclaim_mode will be rarely enabled it is unreasonable for all
machines to take a penalty. Fortunately, the zone_reclaim_mode() path
is already slow and it is the path that takes the hit.
