freedreno/a6xx: use nonbinning VS when GS is used
The current "ds = state->bs" seems broken, and the "vs = state->bs" is
unnecessary (already set above). Since it was added as part of a GS-related
patch, I think this is what was intended.
Note: tesselation disables GMEM rendering so we shouldn't have to worry
about hs/ds + binning interaction.
