[POWERPC] spufs: decouple spu scheduler from spufs_spu_run (asynchronous scheduling)
Change spufs_spu_run so that the context is queued directly to the
scheduler and the controlling thread advances directly to spufs_wait()
for spe errors and exceptions.
nosched contexts are treated the same as before.
Fixes from Christoph Hellwig <hch@lst.de>
