Remove an overly-careful check on an enum value being greater than zero. The check was added back in the day when this value was declared as `int` and thus could easily be assigned anything. The check for the upper limit was kept, and augmented with a `BLI_assert()` so that failures here will actually go noticed and can get fixed. No actually functional changes. The data being checked is purely runtime, and is assumed to be generated correctly already. Pull Request: https://projects.blender.org/blender/blender/pulls/134736
