* spu/syscalls.c: Change __send_to_ppe to return the result stored
        in stored in slot 0 of the data, rather than have each assisted
        call retrieve the value.
        * spu/jsre.h: Remove the now unused syscall_out_t.
        * spu/access.c: Use the __send_to_ppe result instead of the slot 0
        value, remove unused syscall_out_t variable.
        * spu/close.c: Ditto.
