[Piglit] [PATCH 23/34] registry/gl.py: Don't try to compare None and not-None

[Dylan Baker]

Python2 allows the comparison of completely unlike types always. Often
the rules for these comparisons are surprising. None is one of the most
surprising comparisons you can make.

In python3 a much more sensible approach was taken, only related types
can be compared. So int and float can be compared, but int and None
cannot.

The solution here is to fail if the value is None, since the comparison
expects None to be less than the other value.
