Let's move operations that are only valid after the backend has been
realized to a ->device_plugged callback, just as virtio-pci does.
Also reorder setting up the host feature bits to the sequence used
by virtio-pci.
While we're at it, also add a ->device_unplugged callback to stop
ioeventfd, just to be on the safe side.
