In some cases, effective_multixact_freeze_max_age can be 0, which presents a division-by-zero hazard for the multixact ID age score calculation. To fix, bump it to 1 in that case so that we use the multixact ID age as the score. While at it, also document that this component score scales due to high multixact member space usage.
