Gustavo A. R. Silva 8fddc4b660 drm/gud: Use size_add() in call to struct_size() 
If, for any reason, the open-coded arithmetic causes a wraparound, the
protection that `struct_size()` adds against potential integer overflows
is defeated. Fix this by hardening call to `struct_size()` with `size_add()`.
