net/ena: fix SIGFPE with 0 Rx queue

Browse Source 
When the number of rx queues is 0 (what can be when application does
not receive) failed with SIGFPE.
It happens when the application is also requesting ETH_MQ_RX_RSS_FLAG
in the rte_dev->data->dev_conf.rxmode.mq_mode.
Fixed adding zero rx queues check.
