net/mlx5: fix multi-process port ID

Browse Source 
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.

Fixes: 2eb4d0107a ("net/mlx5: refactor PCI probing on Linux")
