vbo: Preserve vbo_save::no_current_update on primitive restart.

With this change we preserve the no_current_update property when we
observe a glPrimitiveRestart call. That means that we now also get the
no_current_update optimization for display lists that are made
out of indexed draws using primitive restart.
