### Description of PR
Currently in method flushOrSync, it will only increase fsyncCount once when
`isSync == true`.
But actually we fsync twice when `checksumOut != null` and
`streams.getDataOut() != null`. So we should increase fsync count twice.
> Metrics fsyncCount should be computed correctly in flushOrSync
