Kees Cook 86dd9fd52e LSM: Avoid warnings about potentially unused hook variables 
Building with W=1 shows many unused const variable warnings. These can
be silenced, as we're well aware of their being potentially unused:

./include/linux/lsm_hook_defs.h:36:18: error: 'ptrace_access_check_default' defined but not used [-Werror=unused-const-variable=]
   36 | LSM_HOOK(int, 0, ptrace_access_check, struct task_struct *child,
      |                  ^~~~~~~~~~~~~~~~~~~
security/security.c:706:32: note: in definition of macro 'LSM_RET_DEFAULT'
  706 | #define LSM_RET_DEFAULT(NAME) (NAME##_default)
      |                                ^~~~
