drivers/net/cpmac.c: Correct code taking the size of a pointer

Browse source 
sizeof(dev->dev_addr) is the size of a pointer.  On the other hand,
sizeof(pdata->dev_addr) is the size of an array, so use that instead.

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,...)
// </smpl>
