Correct pO2 formula in CNS calculation.

Browse source 
In commit e58f54cac1 ("Fix ATM-vs-bar confusion") Linus broke the CNS
calculations; The partial pressure is fraction of gas times ambient
pressure, not divided by.

[Dirk Hohndel: identical patch sent by Robert and Anton; I combined the
               commit messages and added the ACK from the perpetrator]
