[Qemu-ppc] [PATCH 42/47] ppce500_spin: Replace open-coded CPU loop with qemu_get_cpu() |

Potentially env could be NULL whereas cpu would still be valid and
correspond to a previous env.
Wrapping this in qemu_get_cpu(), env is no longer needed, so simplify
code that existed before 55e5c2850293547203874098f7cec148ffd12dfa.
