OpenSubdiv: Completely disable topology verification

Previously it was enabled for debug builds, now it is to be enabled
explicitly.

The reason for this is to reduce overhead when debugging other areas
which might involve subdivision surface. When conversion is to be
debugged set this manually in the code.
