lapb: Neaten debugging

Enable dynamic debugging and remove a bunch of #ifdef/#endifs. Add a lapb_dbg(level, fmt, ...) macro and replace the printk(KERN_DEBUG uses. Add pr_fmt and remove embedded prefixes. Signed-off-by: Joe Perches <[email protected]> Signed-off-by: David S. Miller <[email protected]>
