* [dpdk-stable] [PATCH] net/mlx5: fix rte flow items size calculation

flow_dv_get_item_len returns the actual header size of
an rte_flow item.

Changing any of the structs for rte_flow items by adding
or removing some extra fields will break this function.

This fixes the behavior by retrning the actual header size
of each item.
