[PATCH net-next 7/7] eth: iavf: migrate to new RXFH callbacks

[Jakub Kicinski <kuba@kernel.org>]

Migrate to new callbacks added by commit 9bb00786fc61 ("net: ethtool:
add dedicated callbacks for getting and setting rxfh fields").

I'm deleting all the boilerplate kdoc from the affected functions.
It is somewhere between pointless and incorrect, just a burden for
people refactoring the code.
