For a single_port_submission context, GVT expects that it can only be submitted to port 0, and there shouldn't be any other context in port 1 at the same time. This is required by GVT-g context to have an opportunity to save/restore some non-hw context render registers. This patch is to workaround GVT-g. v2: optimized code by following Chris's advice, and added more comments to explain the patch. v3: followed the coding style.
