[POWERPC] spusched: Fix null pointer dereference in find_victim
find_victim can dereference a NULL pointer when iterating over the list
of victim spus because list_mutex only guarantees spu->ct to be stable,
but of course not to be non-NULL.
Also fix find_victim to not call spu_unbind_context without list_mutex
because that violates the above guarantee.
