drm/nouveau: Validate channel indices passed from userspace. When hacking the libdrm for improvements, I triggered a kernel crash related to the fact that the NOUVEAU_NOTIFIEROBJ_ALLOC ioctl calls nouveau_channel_get with an unchecked channel index. The patch ensures that the channel index is an unsigned and validates its value in nouveau_channel_get.
