GEODE-3619: fix diskTasksWaiting statistic

Compaction no longer does an extra decrement of the stat.
Unit test confirms the fix.

> For every disk store compaction operation that runs the CachePerfStats.diskTasksWaiting
statistic is decremented. So if this statistics is -10 it tells you that 10 compactions have
completed.
> It is supposed to tell you how many are waiting for a thread so that the can run and
the value of this statistics should always be >= 0.
