net/virtio: fix dev_unplug_pending

.dev_unplug_pending is set up by virtio-net code indepent of failover
support was set for the device or not. This gives a wrong result when
we check for existing primary devices in migration code.

Fix this by actually calling dev_unplug_pending() instead of just
checking if the function pointer was set. When the feature was not
negotiated dev_unplug_pending() will always return false. This prevents
us from going into the wait-unplug state when there's no primary device
present.
