net/mlx5: generate bonding device name

If device is VF LAG bonding one the port name includes
the bonding Infiniband device name and looks like:

  82:00.0_mlx5_bond_0 - for master device port PF0
  82:00.1_mlx5_bond_0_representor_5 - for representor
                                           VF5 over PF1

where bonding Infiniband device mlx5_bond_0 controls
the 82:00.0 as PF0 and 82:00.1 as PF1 PCI functions.
