Igor Sugak 3ad6b794cf rocksdb: Fix 'Division by zero' scan-build warning 
Summary:
scan-build complains with division by zero warning in a test. Added an assertion to prevent this.

scan-build report: http://home.fburl.com/~sugak/latest6/report-c61be9.html#EndPath

Test Plan:
Make sure scan-build does not report 'Division by zero' and all tests are passing.
```lang=bash
% make analyze
% make check
```
