    net/mlx4: fix fast-path ops setup in secondary process
    
    The secondary process MLX4_MP_REQ_START_RXTX handler sets
    dev->rx_pkt_burst and dev->tx_pkt_burst, but does not update
    rte_eth_fp_ops[].rxq.data and txq.data. Since rte_eth_rx_burst()
    uses rte_eth_fp_ops (which is process-local), the secondary
    retains stale queue data pointers after VF hot-add, causing a
    segfault.
    
    Similarly, the MLX4_MP_REQ_STOP_RXTX handler sets dev burst
    functions to dummy but does not update rte_eth_fp_ops burst
    pointers, leaving the secondary calling into freed resources.
    
    Fix by updating rte_eth_fp_ops rxq.data and txq.data in the
    START_RXTX handler, and rte_eth_fp_ops burst function pointers
    in the STOP_RXTX handler.
