[PATCH net-next 1/2] net: stmmac: Pad ring number with zeroes in display_ring()

[Florian Fainelli]

Make the printing of the ring number consistent and properly aligned by
padding the ring number with up to 3 zeroes, which covers the maximum
ring size. This makes it a lot easier to see outliers in debug prints.
