Probably by coincidence more than anything we decided to make the bsd ring have the default *other* flush. As the new vebox ring exposes, the bsd ring is actually the weird one. Doing this allows us to call gen6_ring_flush for the vebox because calling blt_ring_flush would be weird... This patch should have no functional change.
