Move all remaining elements that were unique to execlists queue items in to the associated request. Issue: VIZ-4274 v2: Rebase. Fixed issue of overzealous freeing of request. v3: Removed re-addition of cleanup work queue (found by Daniel Vetter) v4: Rebase. v5: Actual removal of intel_ctx_submit_request. Update both tail and postfix pointer in __i915_add_request (found by Thomas Daniel) v6: Removed unrelated changes Signed-off-by: Nick Hoath <nicholas.hoath@intel.com> Reviewed-by: Thomas Daniel <thomas.daniel@intel.com> [danvet: Reformat comment with strange linebreaks.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
