During certification, manufacturers are required to demonstrate that dumped fuel cannot impinge on the aircraft structure in any flight conditions, so there is no inherent danger in dumping fuel with an in-flight fire.
That said, with a fire on board, the time used flying around dumping fuel might be more prudently spent in getting the aeroplane on the ground ASAP instead.
