net/mlx5: update PCI address retrieving routine

Browse Source 
The routine mlx5_ibv_device_to_pci_addr() takes Infiniband
device list object, takes the device sysfs path from there
and retrieves PCI address. The routine may be implemented
in more generic way by taking sysfs path directly as parameter
and can be used for getting PCI address of netdevs.

The generic routine is renamed to mlx5_dev_to_pci_addr()
