drivers/net/typhoon.c: delete double assignment 

Author: Julia Lawall <julia@diku.dk>

Delete successive assignments to the same location.  The current definition
does not initialize the respRing structure, which has the same type as the
cmdRing structure, so initialize that one instead.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// 
@@
expression i;
@@

*i = ...;
 i = ...;
//
