drm/nouveau: check ioctl command codes better
nouveau_drm_ioctl() only checks the _IOC_NR() bits in the
DRM_NOUVEAU_NVIF command, but ignores the type and direction bits, so any
command with '7' in the low eight bits gets passed into
nouveau_abi16_ioctl() instead of drm_ioctl().
Check for all the bits except the size that is handled inside of the
handler.
