V4L/DVB (13610): uvc: Correct size given to memset

Browse source 
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/)

// <smpl>

type T;
T *x;
expression E;

memset(x, E, sizeof(
+ *
 x))
// </smpl>
