Work around ndr_unpack failing on structures with relative pointers.
This disgusting hack works around the fact that ndr_pull_struct_blob_all will always fail on structures with relative pointers. So, map ndr_unpack to ndr_pull_struct_blob_all only if we don't have any relative pointers in this structure. Andrew Bartlett
