In case of PCI-PT the mac address of the port should be flushed when the Vm attached to it is deleted

Bug #1607369 reported by Preethi Dsilva on 2016-07-28

Bug Description

1.brought up a pci-pt setup
2.Created a pci-pt port (it is assigned a mac starting with fa:)
3.now boot a Vm with port
4.on successful boot ,port created in step 2 gets mac of the nic of compute
5.now delete the vm ,we see that even though Vm is deleted The port still contains mac of the compute nic
6.if we would want to boot a new vm on the same compute ,we will need to either use the same port or first delete the port created in step 2 and create new port.

Ideal scenario would be once vm is deleted ,The mac associated with the port (compute nic mac) should be released.
