vdpa: Add SetSteeringEBPF method for NetClientState
At present, to enable the VIRTIO_NET_F_RSS feature, eBPF must be loaded for the vhost backend. Given that vhost-vdpa is one of the vhost backend, we need to implement the SetSteeringEBPF method to support RSS for vhost-vdpa, even if vhost-vdpa calculates the rss hash in the hardware device instead of in the kernel by eBPF. Although this requires QEMU to be compiled with `--enable-bpf` configuration even if the vdpa device does not use eBPF to calculate the rss hash, this can avoid adding the specific conditional statements for vDPA case to enable the VIRTIO_NET_F_RSS feature, which reduces code maintainbility.
