Subject: i40e: add function header for i40e_get_rxfh
Patch-mainline: v4.15-rc1
Git-commit: 21675bdc214b34d2ce4e30396e9ff36f0e61ae93
References: bsc#1101816 FATE#325147 FATE#325149

Someone left this poor little function naked with no header.  This
dresses it up in a proper function header it deserves.
