Move maxNumDataBytes and maxNumEcBytes calculation to fix crash
The blocks.Add will std::move the unique_ptrs, so the std::max calculations
need to go before. Without this change, pdfium_test will crash when trying
to render test/barcode_test.pdf with XFA enabled.
Tested that after this change, barcode_test.pdf is rendered without crashing.
