Call is expensive, might also be good to improve the function in opm-common. (FaceDir.cpp) I leave that to others though.

This fixes the significant preformance regression in flux calculations that was introduced earlier. On the order of 5% total at least.

Not directly related to OPM/opm-simulators#5318, but I will test both together.
