Description of problem:
static ip remain on the interface when removing non-vm network from it in case it has another vlan network attached.

If attaching to an interface non-VM network + vlan network and setting a static ip on the non-vm network, the static ip is left on the interface, although the non-vm network is detached from the host.
The static ip will be removed from the interface only when detaching the vlan network from the interface. 

- If attaching only a non-vm network to the interface with static ip and then detaching the network, the static ip is removed from the interface as it should be. 

Version-Release number of selected component (if applicable):
vdsm-4.19.7-1.el7ev.x86_64

How reproducible:
100

Steps to Reproduce:
1. Attach vlan network + non-Vm network to the same interface and set static ip on the non-vm network. Approve operation in setup networks dialog 
2. Detach the non-vm network from the interface

Actual results:
The static ip remains on the interface. 

Expected results:
Static ip should be removed if the non-VM network is detached from the interface
