[Mesa-dev] [PATCH] gallium: Reduce trace_dump_box_bytes size by box->x.

If stride is supplied (as either stride or slice_stride), trace_dump_box_bytes will try to read stride bytes, regardless whether start address is offset by box->x. This causes access outside mapped region, and possible segv. (transfer_map stride and layer_stride are not adjusted for box dimensions
