Samuel Merritt 7fe0c6c695 Fix rebalancing when 2+ of a partition's replicas are on deleted devices. ... RingBuilder._reassign_parts assumed that only replica for a given partition would move. This isn't necessarily true in the case where a bunch of devices have been removed. This would leave invalid entries in _replica2part2dev and also cause validation to fail. One easy way to reproduce this is to create a 3-replica, 3-zone, 6-device ring with 2 drives per zone (all of equal weight), rebalance, and then remove one drive from each zone and rebalance again.
