In function i40e_vsi_config_tc_queue_mapping(), if 'enabled_tcmap' is 0,
'total_tc' might be 0. Then 'total_tc' might be used in a division
by 0 in "qpnum_per_tc = i40e_align_floor(vsi->nb_qps / total_tc)".
Fix it by changing 'total_tc' from 0 to 1 just as func
i40e_vsi_update_queue_mapping() does.
