Since unifying ringbuffer/execlist submission to use engine->pin_context, we ensure that the intel_ring is available before we start constructing the request. We can therefore move the assignment of the request->ring to the central i915_gem_request_alloc() and not require it in every engine->request_alloc() callback. Another small step towards simplification (of the core, but at a cost of handling error pointers in less important callers of engine->pin_context). v2: Rearrange a few branches to reduce impact of PTR_ERR() on gcc's code generation.
