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.
