dpdk: VM VHOST tests with rxq>1 failing

Browse Source 
DPDK recently added a check in the virtio driver to make sure that
rxmode->mq_mode == ETH_MQ_RX_NONE. We were passing ETH_MQ_RX_RSS
and the device initialization was not accepted.

The reason for the change in DPDK was that there is no controls
(algorithm, redirection table, hash function). So they thought ETH_MQ_RX_NONE
was the best choice for the value of mq_mode.

Type: fix
Ticket: VPP-1853
