Fix T42557: Crash on delete or separate vertices with subsurf modifier + vertex parenting 

Only fixes the crash actually, real issue is, vparent does not handle deletion of vertices
at all currently... We'd need either some kind of static uuid for vertices, or some
mapping helpers used each time we remove or reorder verts... ugh.

Org patch by Severin (Julian Eisel).
