Problem with InsetMathSideset::dyb

[Jean-Marc Lasgouttes]

Coverity points out that in the code below, des is overwritten without 
being used. The same happens in dyt(). Georg, any comment?

int InsetMathSideset::dyb(BufferView const & bv) const

129        int nd = ndes(bv);
130        int des = 0;
131        if (scriptl_ && scriptr_)
132                des = max(bl().dimension(bv).ascent(), 
br().dimension(bv).ascent());
