Either OVS_CT_SRC_NAT or OVS_CT_DST_NAT is set, OVS_CT_NAT must be set in info->nat. Thus, if OVS_CT_NAT is not set in info->nat, it will definitely not do NAT but returns NF_ACCEPT in ovs_ct_nat(). This patch changes nothing funcational but only makes this return earlier in ovs_ct_nat() to keep consistent with TC's processing in tcf_ct_act_nat().
