llvmpipe: Unmapping vertex/index buffers does NOT flush draw module anymore.
Not since 6094e79f4e3350d123c7532b1c73faa60834a62d. Drivers now need to flush draw module explicitely (which explains why all those previous commits adding draw_flushes calls were necessary). This is a good thing, but it's tricky to get this right in face of user buffers (it's not even clear who has the responsibility to flush when a user buffer is seen -- statetracker or pipe driver), so just force flush (temporarily) since it's not a bottleneck now.
