We need to do this before computing landIceMask. Otherwise, critical passages cannot be used to open up channels of open ocean through areas covered by (grounded) land ice.

We need to do this before computing `landIceMask`.  Otherwise,

Testing

I tested this in conjunction with #807 and MPAS-Dev/geometric_features#203. I am (finally!) able to get the desired behavior close to the Carroll Inlet.

On the culled mesh, here is landIceFracObserved:
landIceFracObs

And here is landIceMask:
landIceMask

See #844 for details on how it looked without the critical passage.

@darincomeau, could you give this a quick look? Do we finally have something an Stange that we can live with?

What got missed here is also setting landIcePressure to zero in these critical passages.
