    drm/i915: Avoid context dereference inside execlists_submission_tasklet
    
    A lesson that has to be relearnt over and over again is that the request
    does not keep a reference to the context and so we cannot freely
    dereference the context from inside the execlists_submission_tasklet. In
    particular, we try to do so in the new GEM_TRACE() so convert those over
    to the port->context_id we keep for GEM debugging. This means the
    tracing now depends on DRM_I915_GEM_DEBUG.
    
    Fixes: bccd3b831185 ("drm/i915: Use trace_printk to provide a death rattle for GEM")
