DX solver doesn't invalidate mClothDatas after sorting cloth instances

[BartmanAbyss]

NvCloth/NvCloth/src/dx/DxSolver.cpp

Lines 268 to 278 in d6d7175

	void cloth::DxSolver::addClothUpdateData()
	{
	// sort cloth instances by size
	ps::sort(mCloths.begin(), mCloths.size(), ClothSimCostGreater(), ps::NonTrackingAllocator());
	DxContextLock contextLock(mFactory);
	// resize containers and update kernel data
	mClothDataHostCopy.resize(mCloths.size());
	mClothData.resize(mCloths.size());
	mFrameDataHostCopy.resize(mCloths.size());

needs

	// maybe we got sorted
	for(auto& cd : mCloths)
		cd->notifyChanged();

afterwards.

Without the fix it crashed the GPU.
