From: Viacheslav Ovsiienko 
> If RSS action contains non zero hash key length and NULL key buffer pointer the
> default hash key should be used.
> The check for the NULL pointer this was missing in the mlx4 PMD causing
> crash, for example, in testpmd with command:
> 
> flow validate 0 ingress group 0
>   pattern eth / ipv4 / end
>   actions rss queues 0 end key_len 40 / end
> 
> Fixes: ac8d22de2394 ("ethdev: flatten RSS configuration in flow API")
