Andre Detsch ada83daab3 [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outdated NPC value was being (re)written to the SPU.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.
