I looked at env/io_posix.cc:522 but don't see a reason why the line needs to be there at all, because it is not used before overwritten. So it must be a line that is put there as a bug. Remove it.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6135

Test Plan: Rerun the same test which passes after the fix. Run all the tests and make sure they all pass.
