Subject: [PATCH] btrfs: return the actual error value from  from
 btrfs_uuid_tree_iterate

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.
