Description of problem:
It is possible to assign 2 interfaces on one host with same IP address

Version-Release number of selected component (if applicable):
oVirt Enterprise Virtualization Engine Manager Version: 3.1.0_0001-9.el6ev 

How reproducible:
100%

Steps to Reproduce:
1. create 2 logical networks
2. hosts-> your host-> Network Interfaces -> Setup Hosts Networks -> attach NICs to logical networks
3. assign interfaces with same IP

  
Actual results:
2 interfaces can be assigned with same IP

117: 1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
    link/ether d0:67:e5:f0:7f:30 brd ff:ff:ff:ff:ff:ff
    inet 10.34.67.106/27 brd 10.34.67.127 scope global 1
    inet6 fe80::d267:e5ff:fef0:7f30/64 scope link 
       valid_lft forever preferred_lft forever
119: 2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
    link/ether 90:e2:ba:04:28:b8 brd ff:ff:ff:ff:ff:ff
    inet 10.34.67.106/27 brd 10.34.67.127 scope global 2
    inet6 fe80::92e2:baff:fe04:28b8/64 scope link 
       valid_lft forever preferred_lft forever

Expected results:
it should be not possible to assign same IP on 2 interfaces for 1 host
