Fix buffer bugs affecting transform feedback. Running dEQP-GLES3.functional.transform_feedback would trigger a few assertion failures because of some regressions that crept into our code. Among the regressions is assuming we can't map a buffer that has no underlying storage object. This is valid since we sometimes allow setData without creating a native storage. Additionally we should free our existing data store on a new call to SetData, to prevent old but "new" data revisions from complicating our storage.
