btrfs: return the actual error value from from btrfs_uuid_tree_iterate


[ 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.
