Subject: [PATCH -mmotm] kptr_restrict: fix build when PRINTK not enabled

From: Randy Dunlap <randy.dunlap@...cle.com>

#include <linux/printk.h> since that is where kptr_restrict is externed.

Put kptr_restrict inside #ifdef CONFIG_PRINTK block to fix build error
when CONFIG_PRINTK is not enabled:

kernel/sysctl.c:712: error: 'kptr_restrict' undeclared here (not in a function)
