From: Steve Yang <stevex.y...@intel.com>
The flag RTE_ETH_DEV_CLOSE_REMOVE is set so all port resources
can be freed by rte_eth_dev_close().
Freeing of private port resources is moved
from the ".remove(device)" to the ".dev_close(port)" operation.
Signed-off-by: Steve Yang <stevex.y...@intel.com>

[Thomas] Note: freeing in secondary process is inconsistent
between .dev_close and .remove operations.
