Revert "Ensure that XFA Pages always have a corresponding PDF page"
This reverts commit e7207f33f8024b59fc85abb1b4594b0fbab5361b.
Reason for revert: Causes crash in some XFA forms - crbug.com/840922
This is a merge, not a clean revert.
Original change's description:
> Ensure that XFA Pages always have a corresponding PDF page
>
> The PDF page may be blank, un-numbered, or untracked by CPDF, but
> this provides a place for all XFA pages to "extend" from down the
> road.
