[Qemu-ppc] [PATCH 41/47] e500: Replace open-coded loop with qemu_get_cpu() |

Since we still need env for ppc-specific fields, obtain it via the new
env_ptr fields to avoid "cpu" name conflicts between CPUState and
PowerPCCPU for now.
This fixes a potential issue with env being NULL at the end of the loop
but cpu still being a valid pointer corresponding to a previous env.
