Description of problem:
Trying to create bond on host via webadmin -> Setup Hosts Networks 
returns following error:
Error while executing action Setup Networks: Unexpected exception (see screenshot)
error messages from logs are bellow

this probably happens because "bond" interfaces are not created on host when host is added to setup any more


Version-Release number of selected component (if applicable):
oVirt Engine Version: 3.3.0-0.2.master.20130710172219.git240a5ed.fc18 
vdsm-4.11.0-123.gitdd3f6ca.fc18

How reproducible:
100%

Steps to Reproduce:
1. add new host to setup (make sure it does not have any bond* interfaces defined)
2. Hosts -> your host -> network interfaces -> setup host networks
3. create bond (e.g. bond1), no need to attach network -> click ok -> click OK

Actual results:
cannot create bond

Expected results:
bond should be created
