Subject: [PATCH] examples/flow_filtering: add flow director config for i40e

[ upstream commit 9a93446a0e8c7e95504ff0bfd26d139a8c1ef320 ]

Rte_fdir_conf of rte_eth_conf should be initialized before
port initialization. It is a workaround solution when working
with Intel I40e.

Fixes: 4a3ef59a10c8 ("examples/flow_filtering: add simple demo of flow API")
