    Provide correct fip cidr when deleting port forwarding
    
    The second parameter of fip_id_cidrs requires a cidr, but now is address. this
    causes function `_sync_and_remove_fip` fail to remove vip as expected.
    
    if current is ha router, in function _sync_and_remove_fip will call
    `ri._remove_vip(fip_id_cidr[1])`. the final parameter is passed to
    KeepalivedInstance.remove_vip_by_ip_address and compare with attribute vips.
    the values of vips are of type CIDR.
    
    if not ha, the following process processing use netaddr.IPNetwork and can be
    performed as expected.
