net: sgi: ioc3-eth: remove checkpatch errors/warning
Before massaging the driver further fix oddities found by checkpatch like - wrong indention - comment formatting - use of printk instead or netdev_xxx/pr_xxx Signed-off-by: Thomas Bogendoerfer <tbogendoerfer@suse.de> Signed-off-by: David S. Miller <davem@davemloft.net>
