Having second thought on this, I'll go only with
s/ice_xsk_pool/ice_rx_xsk_pool/ to align with Tx side. Tx side also lacks
the 'set' keyword in its naming, but I don't want to touch this here.
I currently don't see a reason for these functions being inlined as we are
not setting xsk pool pointers in the hot path at all, therefore I can go
later on with a patch dedicated for -next that fixes naming and drops the
inlining.
