tdf#142693 DOCX import: fix zeroing huge page sizes

which bigger than 2^15 twips (> ~57.8 cm).

Regression from commit 4d1621136c464b462a598571ecdcfe2ae119d8c7
"Fix ignoring large twips values like MSO does (cp#1000087)".

Note: Writer could export page size up to 600 cm × 600 cm,
and now it can import it back as well. It can even import
page sizes in kilometers, and display that, but there will
be other issues about its display. MS Word couldn't save
page size over 2^15, but can import, and display them till
up to 2^16 (that is about 116 cm).
