Under multi-process scenario, the secondary process gets queue state
from the wrong location (the global variable 'ports'). Therefore, the
secondary process can not forward since "stream_init" is not called.
This commit fixes the issue by calling 'rte_eth_rx/tx_queue_info_get'
to get queue state from shared memory.
