0020951: EDF 1501 SMESH: Conversion linear/quadratic with medium nodes on geometry fails with GHS3D

Browse Source 
* Fix for usecase: open the atached study, convert Mesh_1 from
   quadratic, unassign GHS3D algo -> SIGSEGV. Reason is that the same
   SMDS_SpacePosition is shared by all nodes in different solids.
