vfs catia: Fix a NULL dereference when CATIA is loaded with no mappings specified.
When we use the CATIA vfs module and don't have any mapping specified,
we return NULL for the mapped_name, thereby resulting in segfaults.
When we don't have catia mapping, we should just use the old name
instead of returning NULL for the mapped_name.
