staging/sbe-2t3e3: Use netdev_ or dev_ or pr_ printks in module.c

fixed below checkpatch warning.
- WARNING: Prefer netdev_err(netdev, ... then dev_err(dev, ... then pr_err(...  to printk(KERN_ERR ...
- WARNING: Prefer netdev_warn(netdev, ... then dev_warn(dev, ... then pr_warn(...  to printk(KERN_WARNING ...

and add pr_fmt.
