Subject: [PATCH] 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.
