drivers/net/usb: Correct code taking the size of a pointer
sizeof(dev->dev_addr) is the size of a pointer. A few lines above, the
size of this field is obtained using netdev->addr_len for a call to memcpy,
so do the same here.
A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>

expression *x;
expression f;
type T;

*f(...,(T)x,...)
