checkpatch: update suggested printk conversions
Direct conversion of printk(KERN_<LEVEL>... to pr_<level> isn't the preferred conversion when a struct net_device or struct device is available. Hint that using netdev_<level> or dev_<level> is preferred to using pr_<level>. Add netdev_dbg and dev_dbg variants too. Miscellaneous whitespace neatening of a misplaced close brace.
