    nv50,nvc0: fix use-after-free when vertex buffers are unbound

    Always reset the vertex bufctx to make sure there's no pointer to
    an already freed pipe_resource left after unbinding buffers.
    Fixes use after free crash in nvc0_bufctx_fence().

I believe this should fix everything. Not sure why you didn't see issues with a
G84... probably gets lucky somehow. Thanks for debugging it and tracking the
issue down!
