When use bond function in mellanox driver environment, we call the
find_port_id_by_pci_addr() function,if we don't add mellanox kernel
driver type in enum rte_kernel_driver, the function will return -1
because kdrv unknown, so we add the mellanox driver type, and when
scan the pci, fill the kdrv to fix this problem.

The issue is not that MLX devices are not properly represented, but
that the find_port_id_by_pci_addr function has a crappy way to recognize
PCI devices.
The find_device bus operator should be used to find a device having
a specific rte_pci_addr. I described something similar not too long
ago[1]. This matching function would benefit from being properly
rewritten.
