[PATCH net] drivers: net: Don't print unpopulated net_device name

[Harvey Hunt]

For ethernet devices, net_device.name will be eth%d before
register_netdev() is called. Don't print the net_device name until
the format string is replaced.

I've tested this patch on a board that has a DM9000, but haven't 
tested the other two network devices.
