Pass VF MAC address to ovs to set in case of netdev VIFHostDevice. In case of DPDK representor port, Nova will pass through the VF PCI as a hostdev and os-vif should pass the MAC to ovs as it would be responsible for setting its MAC. Moreover, when not using dpdk, libvirt does the mac cleanup, since the VF is managed by libvirt, but when using DPDK, libvirt does not manage the VF so we need to cleanup MAC address in os-vif.
