Update the mergeable buffers paramaters in performance tuning to the correct parameter mrg_rxbuf.

By not reserving multiple + mrg_rxbuf=off to the QEMU command line options. By not reserving multiple chains of descriptors it will make more individual virtio descriptors available for rx to the guest using dpdkvhost ports and this can improve performance.
