Campbell Barton 77e3eac389 Fix for old bug with subsurf not initializing normals for edges that had no faces,
Noted that a floating point exception caused by this r28953.

With the render engine using DerivedMesh normals this came up as a memory error when rendering some files.

for now zero the normals, could interpolate between vertex normals if needed.
