[BUG] Abnormal rate limit with mqtt

Describe the bug
The gateway has abnormal rate limit when connect to thingsboard by mqtt.
It is an logic caused bug, and in fact, it is a problem with the python-client-sdk repository.

Error traceback (If available):
The sleep function indicated by the arrow in the diagram below will always be cross-triggered.
That means the mqtt-sending rate will always be limited to 10 per second since the function _publish_data always wait_for_publish.

Hi @yfPanne,
