Currently, after a failed allocation, the metaslab code recalculates the weight for a metaslab. However, for space-based metaslabs, it uses the maximum free segment size instead of the normal weighting algorithm. This is presumably because the normal metaslab weight is (roughly) intended to estimate the size of the largest free segment, but it doesn't do that reliably at most fragmentation levels. This means that recalculated metaslabs are forced to a weight that isn't really using the same units as the rest of them, resulting in undesirable behaviors. We switch this to use the normal space-weighting function.
