In the Auto / Fixed SP mode all three values are zero, and stays zero
during the hole dive.

This fix isn't bug-free, eg if a sensor gets disconnected during a dive,
we should report zero for that, but it feels like the lesser evil than
the current code.


I dropped a mail to HW suggesting to just not log any sensors in Auto /
Fixed SP mode which would kinda make sense. Right now the HwOS based
devices logs ppo2 in all CCR modes.
