sfc: Fold falcon_probe_nic_variant() into falcon_probe_nic()
falcon_probe_nic_variant() does a lot less than it used to, and a lot less than it claims to. Fold the remainder into its caller. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
