Propagate duplicate IF addr add/del error up to API.
Identify and complain when the same IP prefix is assigned
to two different SW interfaces:
vpp# set int ip address TenGigabitEthernet6/0/0 1.2.3.4/32
vpp# set int ip address TenGigabitEthernet6/0/1 1.2.3.4/32
set interface ip address: Prefix 1.2.3.4/32 already found on
interface TenGigabitEthernet6/0/0
