Fix #21850: Modifier applied to surface doesnt work when only a curve.

I removed 3D flag checking for DL_POLY displists in nurbs-to-mesh conversion
function -- DL_POLY displist should be always converted to edge loop.
DL_POLY which should be converted to something else is odd i think.

This commit also fixes trouble cyclic surface curve to mesh conversion problem.
