Nicholas Piggin afee27f382 irq_work: Do not raise an IPI when queueing work on the local CPU 
[ Upstream commit 471ba0e686cb13752bc1ff3216c54b69a2d250ea ]

The QEMU PowerPC/PSeries machine model was not expecting a self-IPI,
and it may be a bit surprising thing to do, so have irq_work_queue_on
do local queueing when target is the current CPU.
