Review Comment:
in normal cases, `compressedDirectBuf`'s `limit` will be correctly reset at
here, but when decompressing corrupt data,
`zstdJniCtx.decompressDirectByteBufferStream` throws an exception so the code
won't reach here, if `reset` does not correctly clear the state, reusing the
decompressor may cause a problem
> ZStandardDecompressor should reset compressedDirectBuf correctly
