max_body_size逻辑不一致

[imdouyu]

DEFINE_uint64(max_body_size, 64 * 1024 * 1024,
              "Maximum size of a single message body in all protocols");

A message from x.x.x.x:4096(protocol=baidu_std) is bigger than 67108864 bytes, the connection will be closed. Set max_body_size to allow bigger messages

看代码定义说是对所有协议生效，但在测试中发现用h2:grpc没有消息过大的报错，用baidu_std就会有上面的错误，是对h2:grpc不检测吗，这个设计是预期的还是漏了逻辑呢

搜了代码也没发现
