[Skiboot] [PATCH] core/cpu: Fix memory allocation for job array

[Vaidyanathan Srinivasan]

fixes: 7a3f307e core/cpu: parallelise global CPU register setting jobs

This bug would result in boot-hang on some configurations due to
cpu_wait_job() endlessly waiting for the last bogus jobs[cpu->pir] pointer.
