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. Signed-off-by: Tim Prouty <tprouty@samba.org>
