From: Pan Bian bianpan2016@163.com
[ Upstream commit 73ba39ab9307340dc98ec3622891314bbc09cc2e ]
In function btrfs_uuid_tree_iterate(), errno is assigned to variable ret on errors. However, it directly returns 0. It may be better to return ret. This patch also removes the warning, because the caller already prints a warning.
