[poppler] Fix rare segmentation fault in CID font vertical exceptions assignment

[Peter Kerzum]

Good morning!

While using xpdf we encountered an error that applies both to xpdf and 
poppler. It seems to be a result of unattended copy-paste - index of 
horizontal exception is applied to vertical

Please consider applying the following patch:
