The device port_id is used for inter-process communication and must
be the same both for primary and secondary process
This IPC port_id was configured with the invalid temporary value in
port spawn routine. This temporary value was used by the function
rte_eth_dev_get_port_by_name() to check whether the port exists.
This commit corrects the mp port_id with rte_eth_dev port_id.
