(Optional) More detailed description for this PR(en: English/zh: Chinese).

en: In the ttstream.RecvMsg call, if the incoming context is used as an imported parameter for pipeline.Read, it may lead to a failure of cancel pass-through; if used as an imported parameter for DecodePayload, it may lead to a failure of rpcinfo retrieval.
zh(optional): 在 ttstream.RecvMsg 调用中，如果使用传入的 context 作为 pipeline.Read 的入参，可能导致 cancel 透传失败，作为DecodePayload 入参，则可能导致 rpcinfo 获取失败
