[PATCH 5/11] kernel/sysctl.c: trivial: use BUG_ON

[Julia Lawall]

From: Julia Lawall <julia@xxxxxxx>

Use BUG_ON(x) rather than if(x) BUG();

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@ identifier x; @@
-if (x) BUG();
+BUG_ON(x);

@@ identifier x; @@
-if (!x) BUG();
+BUG_ON(!x);
// </smpl>
