Description of problem:
When there is two networks with different MTU attached to nic/BOND and we removing the network with the highest MTU getVdsCaps not displaying the right MTU.

For example:
NET_MTU_5000 and NET_MTU_9000 attached to BOND2
remove NET_MTU_9000 from the BOND.
getVdsCaps report that BOND2 have 'mtu': '9000', and also for nics eth2 and eth3.

Version-Release number of selected component (if applicable):
vdsm-4.9.6-31.0.el6_3.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Create two networks with MTU - NET-5000 and NET-9000 and attach them to BOND.
2.Open SetupNetworks and remove NET-9000 from the BOND.

  
Actual results:
getVdsCaps report that the BOND mtu is 9000 and the nics mtu is 9000

Expected results:
getVdsCaps should report that the BOND mtu is 5000 and the nics mtu is 5000
