remove unused code

Summary:
fixup 6a541afcc4. This code didn't do anything because (1) `bytes_per_sync` is assigned in `EnvOptions`'s constructor; and (2) `OptimizeForCompactionTableWrite`'s return value was ignored, even though its only purpose is to return something.
Closes https://github.com/facebook/rocksdb/pull/3055
