drivers/net/ipg.c: remove unused variable 

Author: Julia Lawall <julia@diku.dk>

The variable gig is initialized but never used otherwise.

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// 
@@
type T;
identifier i;
constant C;
@@

(
extern T i;
|
- T i;
  <+... when != i
- i = C;
  ...+>
)
//
