target: remove unneeded array

Delete a local array that is only used to be initialized by memset.

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

// <smpl>
@@
identifier x;
type T;
@@

{
... when any
-T x[...];
<+... when != x
- memset(x,...);
...+>
}
// </smpl>
