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.
