[Mesa-dev] [PATCH 5/5] st/mesa: don't update unrelated states in non-draw calls such as Clear

From: Marek Olšák <marek.olsak at amd.com>
If a VAO isn't bound and u_vbuf isn't enabled because of the Core profile,
we'll get user vertex buffers in drivers if we update vertex buffers
in glClear. So don't do that.
This fixes a regression since disabling u_vbuf for Core profiles.
