Unix: QPageSetupDialog: Use print device default paper size

When invoking QPageSetupDialog from QPrintPreviewDialog, don't construct
a new QPageSetupDialog every time the pageSetup action is triggered, instead
reuse the dialog if it's already been created. This way setPrinter is called
only once. This matches how QPrintDialog invokes QPageSetupDialog.

Set the default print device paper size in initPageSizes() instead of
setPrinter().
