Description of problem:
When adding nic to VM and the add operation fails the MAC address from the failed add nic cannot be used again.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Create VM with 1 nic and start the VM
2.while the VM is up hot-unplug the nic and change the MAC address (one operation)> should fail > Bug 904840
3.Create a new nic with the same MAC address from step 2.
Fail with error MAC Address is already in use.
MAC address should be free and can add to new nic.
This scenario is really a corner case on other bugs since there is no reason to fix it, what should be fixed are the scenarios that caused MAC change to fail.
