Quan Nguyen 09a7bab68b docs: i2c: slave-interface: return errno when handle I2C_SLAVE_WRITE_REQUESTED
In case backend is not ready, ie: fail to wakeup or initialization, on
the returning of the I2C_SLAVE_WRITE_REQUESTED event, bus driver should
aware the backend status and might auto sending NACK on the next
incoming bytes for I2C master to retry.
