In case an image editor is open in the same window, entering sculpt mode
could crash. The cause is that the 3d viewport can request the sculpt
data vbo and its batch. But the image editor doesn't need it and removes
the sculpt data vbo, but doesn't remove the batch. Next frame the batch
could point to invalid data.
This fix will not keep the batch around so it is always being
reconstructed. A better solution needs to be found as the removal of the
vbo is done in a strange part, and the vbo should be checked against the
cd needed over time.
