[PATCH 4/9] mm: remove unnecessary reclaimability check from NUMA balancing target

[Johannes Weiner]

NUMA balancing already checks the watermarks of the target node to
decide whether it's a suitable balancing target. Whether the node is
reclaimable or not is irrelevant when we don't intend to reclaim.
