commit 6050d47a upstream. When ext4_handle_dirty_dx_node() or ext4_handle_dirty_dirent_node() fail, there's really something wrong with the fs and there's no point in continuing further. Just return error from make_indexed_dir() in that case. Also initialize frames array so that if we return early due to error, dx_release() doesn't try to dereference uninitialized memory (which could happen also due to error in do_split()).
