    fixed_configured=True when Add/Remove port IPs

    When updating a port with the fixed_ips request the
    fixed_configured argument should be set to true when
    calling _ipam_get_subnets() so that all subnets are
    returned if host is not set.

    Otherwise the ip allocation will be deffered and an
    empty list of possible subnets for the port is
    returned. Which in turn led to raising an error that
    the network requires subnets to allocate an IP
    address.
