net/mlx5: fix leak when configured repeatedly

Browse Source 
Currently, configuring a mlx device, it will allocate its
own process private in mlx5_proc_priv_init() and only frees
it when closing the device. This will lead to a memory leak,
when a device is configured repeatedly.

For example:
for(...)
do
    rte_eth_dev_configure
    rte_eth_rx_queue_setup
    rte_eth_tx_queue_setup
    rte_eth_dev_start
    rte_eth_dev_stop
done
