When MPLS modification support was added [1], the "tag_index" field was
added into "rte_flow_action_modify_data" structure.
As part of this change, the "RTE_FLOW_FIELD_TAG" type moved to use it
for tag array instead of using "level" field.
Using "level" is still supported for backwards compatibility when
"tag_index" field is zero.
The "mlx5_flow_field_id_to_modify_info()" function calls
"flow_hw_get_reg_id()" function with "level" without checking first
whether "tag_index" field is valid.
This patch calls first to "flow_tag_index_get()" function to get the
index before sending it to "flow_hw_get_reg_id()" function.
