Even if eBPF is not available, virtio-net can perform RSS on the
user-space if vhost is disabled although such a configuration results in
a warning. If vhost is enabled, the configuration will be rejected when
realizing the device. Therefore, VIRTIO_NET_F_RSS should not be cleared
even if eBPF is not loaded.
