Staging: wlan-ng: fix Correct size given to memset 

Author: Julia Lawall <julia@diku.dk>

Memset should be given the size of the structure, not the size of the pointer.

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

// 
@@
type T;
T *x;
expression E;
@@

memset(x, E, sizeof(
+ *
 x))
//
