4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Josef Bacik <jo...@toxicpanda.com>
commit 4559b0a71749c442d34f7cfb9e72c9e58db83948 upstream.
If we're trying to make a data reservation and we have to allocate a
data chunk we could leak ret == 1, as do_chunk_alloc() will return 1 if
it allocated a chunk. Since the end of the function is the success path
just return 0.
