dynamic_debug.h/kernel.h: Remove KBUILD_MODNAME from dynamic_pr_debug

Browse Source 
If CONFIG_DYNAMIC_DEBUG is enabled and a source file has:

#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
#include <linux/kernel.h>

dynamic_debug.h will duplicate KBUILD_MODNAME
in the output string.

Remove the use of KBUILD_MODNAME from the
output format string generated by dynamic_debug.h

If CONFIG_DYNAMIC_DEBUG is not enabled, no compile-time
check is done to printk/dev_printk arguments.

Add it.
