Bonding two interfaces finishes without any error, but bond is not created.

Issue

• After a hypervisor was successfully registered to RHEV-M, the interface that uses "rhevm" network is bonded from the GUI. Bonding process finishes without any error in GUI, but looking at the GUI, I do not see the interface bonded.

• This happens only if the interface used for the "rhevm" network is vlan tagged.

• vdsm.log shows below flow of events. There is an attempt to create bond which fails and reverts back to the previous configuration.
