[Intel-wired-lan] [next PATCH S78-V8 09/12] i40e: make i40evf_map_rings_to_vectors void

[Alice Michael <alice.michael@intel.com>]

From: Mitch Williams <mitch.a.williams@intel.com>

This function cannot fail, so why is it returning a value? And why are
we checking it? Why shouldn't we just make it void? Why is this commit
message made up of only questions?
