[dpdk-stable] [DPDK] net/i40e: fix update PMD close function

[chenxux.di@intel.com]

From: "Di, ChenxuX" <chenxux.di@intel.com>

For each driver where we add flag RTE_ETH_DEV_CLOSE_REMOVE to
eth_xxx_dev_init() to pass the information to the rte_eth_dev_close()
that it should also release the private port resources.

Fixes: 23ea57a2a0ce ("ethdev: complete closing of port")
Cc: stable@dpdk.org
