We will check vm-running state in the generic net layer.
Also we have to flush queues in nic_vmstate_change_handler() when vm state
changes to run. The check here will prevent the flushing process, because
we will check the return value of virtio_net_can_receive in
nic_vmstate_change_handler, When the vdev->vm_running is still false.
Actually it depends on the register sequence of callback functions.
Here nic_vmstate_change_handler will called before virtio_vmstate_change.
So remove the unnecessarily checking.
