IOT_MQTT_Yield 报错，同时导致所在的线程阻塞，非常严重的bug，而且没法规避 #88

ssl recv error: code = -30848, err_str = 表明当前的ssl出错了，需要检查一下ssl出错原因。 云端把SSL连接断开 The peer notified us that the connection is going to be closed

  1. 设备端数据连接过于频繁，触发云端限流，断开设备。 请关闭设备，等待一段时间(5分钟以后)再发起连接
  2. 有多个设备使用相同的product_key和device_name与云端建立连接，之前连接的设备被云端踢开。
  3. 设备端保活出错，没有及时发送MQTT ping packet （出错通常在连接建立1分钟以后）。 如果是保活问题，需要进一步分析。
  4. 如果从未连接成功过，可以考虑是不是大小端口不匹配。 目前SDK 默认是小端，如果在大端环境上工作，请添加定义全局编译条件 REVERSED。

遇到相同问题，yield();这个函数会卡住几十秒。现在publish和yield放在同一个线程，yield阻塞几十秒，导致消息无法及时publish到IOT平台。
