  Currently, when use 'flow' command to create a rule that combine with
several RSS types, even the RSS type combination is invalid, it also
be created successfully.

Here list some invalid RSS combinations:
 - ETH_RSS_IPV4 | ETH_RSS_NONFRAG_IPV4_TCP
 - ETH_RSS_IPV6 | ETH_RSS_NONFRAG_IPV6_TCP
 - ETH_RSS_GTPU | IAVF_RSS_TYPE_INNER_IPV4
 - ETH_RSS_GTPU | IAVF_RSS_TYPE_INNER_IPV4_UDP
 - ETH_RSS_GTPU | IAVF_RSS_TYPE_INNER_IPV4_TCP
 - ETH_RSS_GTPU | IAVF_RSS_TYPE_INNER_IPV6
 - ETH_RSS_GTPU | IAVF_RSS_TYPE_INNER_IPV6_UDP
 - ETH_RSS_GTPU | IAVF_RSS_TYPE_INNER_IPV6_TCP

So, this patch adds these combinations in 'invalid_rss_comb'
array to do valid check, if the combination check failed,
the rule will be created unsuccessful.

Fixes: 91f27b2e39ab ("net/iavf: refactor RSS")
