[PATCH] ppc64: squash EEH warnings

A slightly non-ideal version of the recent patch which fixed EEH being a
no-op went in.  The srcsave variable in eeh_memcpy_to_io() is now never
referenced on non-pSeries machines, and so spews hundreds of warnings.  The
variable doesn't actually accomplish anything, so this patch gets rid of
it.
