Subject: i40e: make i40evf_map_rings_to_vectors void
Patch-mainline: v4.15-rc1
Git-commit: 1b7b7596aeebc21913bad49eb6a2c364c4b2988a
References: bsc#1101816 FATE#325147 FATE#325149

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?
