nv30: falling back to draw path for edgeflag does no good
nv30: falling back to draw path for edgeflag does no good

The problem is that the EDGEFLAG has to be toggled at vertex submission
time. This can be done from either the draw or the regular paths. Avoid
falling back to draw just because there's an edgeflag.
