    Fix creating policy rules from subattributes.

    In case of policy rule checks for rules like e.g.
    "create_port:fixed_ips:subnet" couldn't be created to be
    passed to policy enforcer because policy module could only
    create rule checks for subattributes which are dict types.

    With this patch checks for such rules can be created also for
    attributes which are list of dicts, like e.g. fixed_ips in port
    resource.
