Relax allocation throttling for ditto blocks. Due to random imbalances in allocation it tends to push block copies to one vdev, that looks looks slightly better at the moment. Slightly less strict policy allows both improve data security and surprisingly write performance, since we don't need to touch extra metaslabs on each vdev to respect the min distance.
