`virtio_transport_send_pkt_info` gets all the transport information
from the parameter `t_ops`. There is no need to call
`virtio_transport_get_ops()`.

Remove it.

Fixes: 581512a6dc93 ("vsock/virtio: MSG_ZEROCOPY flag support")

I marked this as net-next material, but honsetly I'm not sure if I
should have targeted net. It's not a bug after all, it's just a cleanup.

Hm, one more suggestion, but not in this patch: may be we can also remove 'struct vsock_sock *vsk' argument
from 'virtio_transport_send_pkt_info()', because it is also included in 'virtio_vsock_pkt_info *info' ?

Thanks

but I think we should drop the Fixes tag.

ok, should I send a v2 without the tag?

Thanks,
