    DVR: Fix TypeError in arp update with allowed_address_pairs

    There is a TyperError seen when trying to update an arp entry
    for the DVR service port that has associated allowed address
    pairs.

    The _get_allowed_address_pair_fixed_ips were not returing the
    fixed_ips dictionary but just returning the fixed_ip string.

    This caused the TypeError to occur. In addition to the fixed_ip
    it should also return the subnet_id for arp_update and it was
    returning it.

    This patch fixes the issues mentioned above.
