When 'SAVAGEFB_DEBUG' is not defined, modify the DBG() macro to use the no_printk() macro instead of using <empty>. This fixes a build warning when -Wextra is used and provides printk format checking:
../drivers/video/fbdev/savage/savagefb_driver.c:2411:13: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
