Instead of looking at plane->fb let's look at the proper new plane state.
Not that the code makes a ton of sense. It's only going through the crtcs in the atomic state, so assuming not all of them are included we're not even calculating the total bandwidth here. Also we're not considering whether each crtc is actually enabled or not.
