dongjiuzhu1 dcb8188f07 driver/spi: avoid calling QPOLL to change rx_length and cause data loss
When the application calls poll and returns the POLLIN event,
QPOLL will be called again during the read operation,
causing rx_length to change and data to be lost.
Therefore, read only need to actively call qpoll to collect driver
data when rx length is 0.
