cnss2: Increase the value of dev power on retry factor

Based on the results of some stress tests under very low
temperature, such as -40degC, the AON voltage on some of the
devices can take more than 1.5s to reach zero. And under
such circumstances, wlan device probe can fail if cnss2 turns
on wlan power supply too fast.

To avoid wlan probe failure, increase the value of wlan power
on retry factor to 4 so cnss2 can wait up to 2s during extreme
conditions before probing the device again.
