[Cbe-oss-dev] [PATCH] cell: fix errno for modular spufs_create with invalid neighbour

[Jeremy Kerr]

At present, spu_create with an invalid neighbo(u)r will return -ENOSYS,
not -EBADF, but only when spufs.o is built as a module.

This change adds the appropriate errno, making the behaviour the same
as the built-in case.

Paulus - pending Arnd's ack, could you send this on for .23?
