Use array_size to protect against multiplication overflows.

The changes were done using the following Coccinelle semantic patch:

// <smpl>
@@
     expression E1, E2;
     constant C1, C2;
     identifier alloc = {vmalloc,vzalloc};
@@
(
       alloc(C1 * C2,...)
|
       alloc(
-           (E1) * (E2)
+           array_size(E1, E2)
       ,...)
)
// </smpl>
