Currently tcf_ct_flow_table_add_action_meta() function assumes that only
established connections can be offloaded and always sets ctinfo to either
IP_CT_ESTABLISHED or IP_CT_ESTABLISHED_REPLY strictly based on direction
without checking actual connection state. To enable UDP NEW connection
offload set the ctinfo and metadata cookie based on ct->status value.
