Fix #109161: Baking freeze with invalid edge array

Browse Source 
The old subsurf DerivedMesh code creates an edge layer
without initializing it, which makes the proper lazy initialization
of the edge layer later think that it's already finished. To avoid that,
remove the edges when creating the DerivedMesh at first.
