  When a RSS rule with symmetric hash function, the RSS type shouldn't
carry with SRC/DST_ONLY. This patch adds invalid RSS type check for
the case.

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

Better to move above check into the below "iavf_any_invalid_rss_type"

  Ok, will move it into " iavf_any_invalid_rss_type" in v2.
