nvc0: disable xfb's which don't have a stride

Browse source 
No stride / no attributes means that nothing is being written to the
buffer. However it might still prevent primitives from being written out
to the other buffers. Disabling it entirely seems to fix it.

Fixes GTF-GL45.gtf30.GL3Tests.transform_feedback.transform_feedback_overflow
