virtio-net: Unlimit tx queue size if peer is vdpa
The code used to limit the maximum size of tx queue for others backends
than vhost_user since the introduction of configurable tx queue size in
9b02e1618cf2 ("virtio-net: enable configurable tx queue size").
As vhost_user, vhost_vdpa devices should deal with memory region
crosses already, so let's use the full tx size.
