drm/nouveau/subdev/bus: Ratelimit logging for fault errors
commit 9887bda upstream. There's plenty of ways to fudge the GPU when developing on nouveau by mistake, some of which can result in nouveau seriously spamming dmesg with fault errors. This can be somewhat annoying, as it can quickly overrun the message buffer (or your terminal emulator's buffer) and get rid of actually useful feedback from the driver. While working on my new atomic only MST branch, I ran into this issue a couple of times. So, let's fix this by adding nvkm_error_ratelimited(), and using it to ratelimit errors from faults. This should be fine for developers, since it's nearly always only the first few faults that we care about seeing. Plus, you can turn off rate limiting in the kernel if you really need to.
