virtio-net: Fix vhost virtqueue notifiers for RSS
virtio_net_guest_notifier_pending() and virtio_net_guest_notifier_mask() checked VIRTIO_NET_F_MQ to know there are multiple queues, but VIRTIO_NET_F_RSS also enables multiple queues. Refer to n->multiqueue, which is set to true either of VIRTIO_NET_F_MQ or VIRTIO_NET_F_RSS is enabled. Fixes: 68b0a6395f36 ("virtio-net: align ctrl_vq index for non-mq guest for vhost_vdpa") Signed-off-by: Akihiko Odaki <akihiko.odaki@daynix.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
