Subject: [PATCH 3/3] Restrict definition of a static function in kernel/auditsc.c

The function 'audit_set_auditable' in kernel/auditsc.c is called
only when the CONFIG_AUDIT_TREE option is set. Therefore, the
following warning may be produced:

kernel/auditsc.c:745: warning: 'audit_set_auditable' defined but not used

This patch fixes the warning by moving the function definition under an
appropriate preprocessor construct.
