    Remove spurious for loop from post deploy j2

    This nested for loop is wrong as it generates all steps for all
    roles twice. This works because yaml parsing ignores the duplicate
    resources, but it's a big waste of space in swift (this fix reduces
    the rendered file size by over 2000 lines with the default roles!)
