Since 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail), there is no need to ever check for the the return value of debugfs_create_file() and drm_debugfs_create_files(). Therefore, remove unnecessary checks and error handling in nouveau_drm_debugfs_init.
These changes also enable nouveau_drm_debugfs_init() to be declared as void.
