Current FreeBSD netback names the interface with xnb<device unit>, but
this is not suitable for usage with the Xen toolstack, which expects
something similar to <prefix><domid><handle>. In order to solve this,
change the netback naming convention to use xnb<domid>.<handle>.

- Prevent trying to unbind if the evtchn has not been bounded.
- Prevent double-freeing xnb->bridge.
- Set the MAC address of the host-facing interface to a dummy value,
so it can work when the interface is added to a bridge.
