Fix T101451: curve attribute overlay disappears when origin is out of view

The core issue seems to be that `BKE_curve_minmax` does not create the
correct bounding box for `Curve` data passed to the render engine.
That's because this `Curve` object does not contain the legacy curve
data structure.

Fixing this will likely require some more consideration, so this fix just
avoids the culling check for now, which is actually also done in
`OVERLAY_extra_wire` using the same approach.
