The scaling of max_avail by the ratio of non-degraded to total objects
count results in the reported max_avail increasing proportionally to the
number of OSDs marked `down` but not `out`. This is counter intuitive
since OSDs going `down` should never result in more space being
available.
Removing the scale factor allows max_avail to remain unchanged until the
OSDs are marked `out`.
