commit 856bd270dc4db209c779ce1e9555c7641ffbc88e upstream.
We are unconditionally returning 0 in cleanup_ref_head, despite the fact that btrfs_del_csums could fail. We need to return the error so the transaction gets aborted properly, fix this by returning ret from btrfs_del_csums in cleanup_ref_head.
