powerpc/spufs: fix missed stop-and-signal event
There is a delay in the transition to the stopped state for class 2
interrupts. In some cases, the controlling thread detects the state of
the spu as running, and goes back to sleep resulting in a hung
application as the event is missed.
This change detects the stop condition and re-generates the wakeup event
after a context save.
