net/szedata2: remove resources when port is closed

Browse Source 
The rte_eth_dev_close() function now handles freeing resources for
devices (e.g., mac_addrs).  To conform with the new close() behaviour we
are asserting the RTE_ETH_DEV_CLOSE_REMOVE flag so that
rte_eth_dev_close() releases all device level dynamic memory.
