[PPC64] Squash EEH warnings

[David Gibson]

Andrew, please apply:

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.
