RDMA/mlx4: Do not fail the registration on port stats
If the FW doesn't support MLX4_DEV_CAP_FLAG2_DIAG_PER_PORT, mlx4 driver
will fail the ib_setup_port_attrs, which is called from
ib_register_device()/enable_device_and_get(), in the end leads to device
not detected[1][2]
To fix it, add a new mlx4_ib_hw_stats_ops1, w/o alloc_hw_port_stats if FW
does not support MLX4_DEV_CAP_FLAG2_DIAG_PER_PORT.
