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

For 'ETH_RSS_IPV4 | ETH_RSS_NONFRAG_IPV4_TCP' (same as IPV6), this
pathch 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")
