Mesh: Avoid unnecessarily initializing corner topology arrays

Browse Source 
This data should be initialized when building the mesh. If the arrays
aren't already initialized, there is already a bug. Theoretically this
could improve performance, since we can use `malloc` instead of
`calloc`. In practice I observed less than a 1% difference though.
