net: Warn for cloned packets in ingress path on SMP systems only



GRO is currently enabled only on SMP systems so move the check for
cloned packets from commit b8a7d12f ("net: Warn for cloned
packets in ingress path") within CONFIG_RPS to prevent printing an
unnecessary warning on single core systems.
