[v2,07/22] net/i40e: enable port detach on secondary process

  Previously, detach port on secondary process will mess primary
process and cause same device can't be attached again, by take
advantage of rte_eth_release_port_private, we can support this
with minor change.

As far as I can see similar changes are done in really many files.
Is it possible to avoid the duplication?
Can it be part of rte_eth_dev_pci_generic_remove() or correctly
