[ Upstream commit a323e5f041dd11af5e3de19ed7ea95a97d588c11 ]
It is not meaningful to poll sta stat when there is no data traffic. So polling sta stat when the device has transmitted data instead to save CPU power.
That implies that it is unallowed the stat_work to work while MCU is being initialized in the really early stage to fix the possible time to time MCU initialization failure.
