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.
