Since 987d65d013 (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.
