## What changes were proposed in this pull request?
Running ozone freon rk with a negative value for --numOfVolumes ,
--numOfBuckets or --numOfKeys does not fail with an error. Instead, the command
prints a progress bar with negative value and hangs.
```
bash-5.1$ ozone freon rk --numOfVolumes=1 --numOfBuckets=1 --numOfKeys=-1
