Don't rely on static data

The ui_enum function gets a const struct obs_ui_info **, which basically
means it expects static data to be used.  I originally had it the other
way around, but yea, it's probably not a good idea, so I'm going to
revert back to the original code instead, which doesn't rely on the data
being static.
