Since 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail), there is no need to check the return value of drm_debugfs_create_files(). Therefore, remove remove unnecessary checks and error handling statement blocks for its return value.
These changes also enable changing drm_debugfs_create_files() to return void.
