cppcheck: fix duplicateBranch

Git history shows it was like this since first commit (2009-12-15)
Moreover I noticed these lines:
    220     if ( mpCGM->pElement->nAspectSourceFlags & ASF_FILLCOLOR )
    221         nFillColor = mpCGM->pElement->pFillBundle->GetColor();
    222     else
    223         nFillColor = mpCGM->pElement->aFillBundle.GetColor();
even if nFillColor can have another value in case below
    249         case FIS_GEOPATTERN :
    250         {
    251             if ( mpCGM->pElement->eTransparency == T_ON )
    252                 nFillColor = mpCGM->pElement->nAuxiliaryColor;
    253             eFS = drawing::FillStyle_NONE;
    254         }
this change is still safe since it's just a simplification.
