[patch] repair failed merges of 2.6.12 in au1000_eth.c

[Ulrich Eckhardt <eckhardt@xxxxxxxxxxxxxx>]

Hi!

Seems a few things went wrong merging 2.6.12 into the l-m.o CVS, leading to 
code duplication. The compiler complains about an unbalanced #ifdef.

Uli

Changes:
 * repair wrong merges of changes from 2.6.12
 * remove an unused variable an an unnecessary set of brackets
