nv50: fix buffer reuse issues

1) We need to insert a barrier between consecutive transform feedback calls.
2) VBO cache needs to be flushed when TFB output is used as VBO draw input.

Fixes Piglit test EXT_transform_feedback/immediate-reuse.

Thanks to Christoph Bumiller for pointing out bugs in previous versions
of this patch.
