cmssw: Crash in DD4hep geometry, step2

@ianna @cvuosalo @civanch #36970 proposes a possible solution to the problem found by @srimanob, which should allow us to move forward in catching other geometry problems in the DD4hep version of D88 step2.
Following the discussion at last simulation meeting, I checked scenario D88 for MTD only (see https://github.com/fabiocos/cmssw/tree/fc-testmtdD88 ) and I confirm there is a crash in the reconstruction geometry of MTD:
To be understood and fixed
