[PATCH 5/5] security/selinux/ss: correct size computation

[Julia Lawall <julia@diku.dk>]

From: Julia Lawall <julia@diku.dk>

The size argument to kcalloc should be the size of desired structure,
not the pointer to it.

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

// <smpl>
@expression@
expression *x;
@@

x =
 <+...
-sizeof(x)
+sizeof(*x)
...+>// </smpl>
