API *rte_eth_link_get* expect to call a wait to complete link_update.
That's the difference between *rte_eth_link_get_nowait*.
The patch fixes the issue that i40e link_update ignores the wait_to_complete flag.
The issue impacts those applications calling rte_eth_link_get to get wrong intermediate link status.
