[Cbe-oss-dev] [PATCH] spufs: fix incorrect initialization of cbe_spu_info.spus

[Jeremy Kerr]

From: Masato Noguchi <Masato.Noguchi at jp.sony.com>

We currently initialize cbe_spu_info[].spus in both init_spu_base and
spu_sched_init. The initialise in spu_sched_init clears the SPU list,
so we end up with no physical SPUs. Because of this, the spu_run
syscall will block forever.

This change removes the unnecessary initialization in spu_sched_init.
