In gen8_emit_flush_xcs, we have to look at all the engines the request
may execute on, and emit an aux-invalidate for each. Currently, we
handle the virtual engine by looking at its engine mask, but that is
copied and refined as the request->execution_mask. If we prefer the
local mask, this is one fewer rq->engine pointer chasing we have to
eliminate later when we remove rq->engine.
