Adrian Bunk 88b9e2bef3 ath9k: work around gcc ICEs (again) 
(I missed the fact that the original post said to apply this patch
twice... -- JWL)

Original commit log message:

This patch works around an internal compiler error (gcc bug #37014) in
all gcc 4.2 compilers and the gcc 4.3 series up to at least 4.3.1
on at least powerpc and mips.

Many thanks to Andrew Pinski for analyzing the gcc bug.
