vf interface isn't assigned the correct mac address

[edan david]

Due to a libvirt change in version libvirt-1.2.18.3-1.fc23.x86_64
Bug ticket for libvirt:
https://bugzilla.redhat.com/show_bug.cgi?id=1372944

the vf interface mac address is not synced with the assigned vf mac address.
when creating a guest with macvtap-passthrough the guest will not get DHCP because the the VF's netdev name is not set.

    Assign mac address to vf netdevice when using macvtap port

    This is a workaround to libvirt issue described here:
    https://bugzilla.redhat.com/show_bug.cgi?id=1372944. The problem is that
    libvirt dosn't update the mac address of the netdevice, instead it uses
    netlink to configure the mac address of the VF. For macvtap to work
    libvirt should set the mac address on the VF net device and using
    netlink. Until this is fixed we should set both of them in nova.
