[POWERPC] spufs: Don't call spu_run_init from spu_reacquire_runnable
This fixes a major bug which was happening when a SPU thread advances
its execution right after being restored to a SPU. A potentially
outdated NPC value was being (re)written to the SPU.
So, spu_run_init, in this case, was either not doing anything relevant,
or breaking the execution of the SPU thread.
This fixes a common problem of losing a mailbox write when it was done
to a saved context.
