developer_volume_miasma: wire the input to the VDB conversion

The VDB from Polygons inside was fed by a bypassed, unconnected Iso
Offset, so the node errored on any input. The input now goes straight
to the conversion and the leftover is gone; a sphere comes out as one
VDB named surface. Same version: no interface.
