virtio-net: check feature before configuring the vq coalescing command
Virtio spec says:
The driver MUST have negotiated the VIRTIO_NET_F_VQ_NOTF_COAL
feature when issuing commands VIRTIO_NET_CTRL_NOTF_COAL_VQ_SET
and VIRTIO_NET_CTRL_NOTF_COAL_VQ_GET.
So we add the feature negotiation check to
virtnet_send_{r,t}x_ctrl_coal_vq_cmd as a basis for the next bugfix patch.
