netdev_printk/dynamic_netdev_dbg: Directly call printk_emit
A lot of stack is used in recursive printks with %pV.
Using multiple levels of %pV (a logging function with %pV
that calls another logging function with %pV) can consume
more stack than necessary.
Avoid excessive stack use by not calling dev_printk from
netdev_printk and dynamic_netdev_dbg. Duplicate the logic
and form of dev_printk instead.
Make __netdev_printk static.
Remove EXPORT_SYMBOL(__netdev_printk)
Whitespace and brace style neatening.
