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.
