When running mlx5_dev_start in mlx5_ethdev the function calls
mlx5_dev_configure_rss_reta in order to configure the rxq's.
Before mlx5_dev_configure_rss_reta there isn't a check whether
there are rxq's and if rxq's are 0 the function fails.
For example, this command:
/build/app/test-pmd/testpmd -n 4 -w 0000:08:00.0,rx_vec_en=0
-- --burst=64 --mbcache=512 -i --nb-cores=27 --txd=2048 --rxd=2048
--vxlan-gpe-port=6081 --mp-alloc=xbuf --rxq 0 --forward-mode=txonly
would fail.
In order to fix this issue, we should call mlx5_dev_configure_rss_reta
only if we have rxq's.
