usbnet: allow type check of devdbg arguments in non-debug build
Improve usbnet's devdbg to always type-check diagnostic arguments,
like dev_dbg (device.h). This makes no change to the resulting size of
usbnet modules.
This patch also removes an #ifdef DEBUG directive from rndis_wlan so
it's devdbg statements are always type-checked at compile time.
