call CDDM_from_BMEditMesh without creating tessface data for modifiers.

- in the case of deform modifiers this is very safe (assuming the mods themselves dont need tessface data), since the DM is freed right after, so this is an easy speedup.

- in the case of bevel and split edge modifiers this should still work out fine since mods that need tessface data will generate it.
