This initialisation of nb_rx_queues and nb_tx_queues has been removed
from eth_virtio_dev_init.
The nb_rx_queues and nb_tx_queues were being initialised in
eth_virtio_dev_init before the tx_queues and rx_queues arrays were
allocated.
The arrays are allocated when the ethdev port is configured and the
nb_tx_queues and nb_rx_queues are initialised.
If any of the following functions were called before the ethdev
port was configured there was a segmentation fault because
rx_queues and tx_queues were NULL:
rte_eth_stats_get
rte_eth_stats_reset
rte_eth_xstats_get
rte_eth_xstats_reset
Fixes: 823ad64795 ("virtio: support multiple queues")
