Clarify deflateReset() documentation.

It previously could have been misinterpreted to mean that parameter
changes after deflateInit2() would be reversed, which is not the
case.

      deflateReset returns Z_OK if success, or Z_STREAM_ERROR if the source
    stream state was inconsistent (such as zalloc or state being Z_NULL).
