Fix CGame CG_WaterLevel() comparisons

My last commit made it so that CGame "waterlevel 1" is feet in water,
but before it was erroneously about waist deep in water. The places
where it is checked it is suppose to be view position underwater.

Change comparisons to use correct value for view position underwater.
