[PATCH] virtio-net: fix module unloading

[Andrew Jones <drjones@redhat.com>]

Unregister the driver before removing multi-instance hotplug
callbacks. This order avoids the warning issued from
__cpuhp_remove_state_cpuslocked when the number of remaining
instances isn't yet zero.

Fixes: 8017c279196a ("net/virtio-net: Convert to hotplug state machine")
