On systems with complex NUMA topologies, the node scoring is adjusted to allow workloads to converge on nodes that are near each other. The way a task group's preferred nid is determined needs to be adjusted, in order for the preferred_nid to be consistent with group_weight scoring. This ensures that we actually try to converge workloads on adjacent nodes.
