Cell: insert dummy field into cell_command_render struct to work around apparent...

Without this dummy field, it seems the SPU code in cmd_render() gets a bogus
value when dereferencing render->num_indices, sometimes.
This showed up as missing tries in gears.c in the first frame rendered.
Using spu-gcc version 4.1.1, Cell SDK 2.1
