[F3D Bleed] Fix rendermode not being reverted

We cannot just assume that othermodeh or othermodel are always setting the same bits, so instead we write the diff of the current cmd to the one already in the reset dict, this means that if a materials sets rendermode and another sets alpha compare (for example) it will still revert the rendermode because those bits will be carried over in the reset dict
