[PATCH] net/virtio-net: reverse unregistering on exit

[Pierre Morel <pmorel@linux.vnet.ibm.com>]

unregister_virtio_driver should be done before the unregistering of
the hotplug state machine callbacks, otherwise the state machine still
holds some instance states at that time.

Let's first unregister the virtio_net_driver first and then the hotplug
state machine callbacks.
