Don't require in-place MAC address update

Previously, we checked that when updating the MAC address that the port
was updated in-place. However, this only works because the port isn't
attached to anything. In a more realistic scenario, updating in-place
actually fails. Remove this check to allow changing the Heat code to
replace the port when the MAC changes.
