    gfileutils: Fix error propagation for other than ENOENT
    
    Commit 6f55306e04e5 unintendedly broke error handling for other
    error conditions than ENOENT along the path, like EPERM. It wanted
    to ignore ENOENT on all elements except the last in the path, but
    in doing that it ignored any other error that might happen on the
    last element.
