Fix T81649: Cloth simulation dynamic area mode tearing the mesh 

Dynamic area should use the radius instead of the initial radius to get
the nodes as the radius can now change during the stroke. In case of
anchored strokes, the current radius can be bigger than the initial
radius, simulating vertices outside the falloff area and breaking the
mesh.
