We need call netif_carrier_off() and do not assume VIRTIO_NET_S_LINKUP
before querying device state during probing, otherwise we may get
wrong operstate after driver was loaded because the link watch event
was not fired as expected.
Since the device state changed could be caught through interrupt, the
unconditional call to nerif_carrier_on() is also removed.
