[PATCH] net/intel: update key_len when getting RSS key

[PATCH] net/intel: update key_len when getting RSS key

[Thierry Herbelot]

When adding the i40e PMD, the rss_hash_conf_get function was changed to
update the RSS key len.
The corresponding functions for ixgbe & e1000 were not updated to
follow the new convention.

Fixes: 8a387fa85f02 ("ethdev: more RSS flags")
