[PATCH ] dynamic_debug: call __netdev_printk only for CONFIG_NET

__netdev_printk is only defined when CONFIG_NET is set. Since we only need
__dynamic_netdev_dbg for network drivers, we can make it conditional on the
same Kconfig symbol.

Previously, if dynamic debug was enabled netdev_dbg() was using
dynamic_dev_dbg() to print out the underlying msg. Fix this by making
sure netdev_dbg() uses __netdev_printk().
