D3D11: Fix primitive topology dirty bit tracking.

syncPrimitiveTopology checks the transform feedback state, so it needs to be called whenever the transform feedback state changes. This fixes flakes in the WebGL 2 conformance test transform_feedback/simultaneous_binding.html Bug: 696345 Change-Id: I4e17bbf60b4a387cc23dc55bd5a051f5da9fa66e Reviewed-on: https://chromium-review.googlesource.com/1006489 Commit-Queue: James Darpinian <jdarpinian@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
