btrfs: uncollapse transaction aborts during renames

During renames we are grouping transaction aborts that can be due to a
failure of one of several function calls. While this makes the code less
verbose, it makes it harder to debug as we end up not knowing from which
function call we got an error.

So change this to trigger a transaction abort after each function call
failure, so that when we get a transaction abort message we know exactly
which function call failed, helping us to debug issues.
