    sw: fix assert in SwObjectFormatterTextFrame
    
    sw/source/core/layout/objectformattertxtfrm.cxx:237: virtual bool 
SwObjectFormatterTextFrame::DoFormatObj(SwAnchoredObject&, bool): Assertion 
`GetPageFrame().GetPhyPageNum() == GetPgNumOfCollected(nIdx)' failed.
    
    The problem is that there are multiple (9) flys on text frame 324.
    
    In the loop in CalcContent(), frame 324 starts out on page 13, then
    with the first/second fly moves to page 12, then with the 3rd fly moves
    forward to page 13 - but the pPageFrame that is passed to
    SwObjectFormatter::FormatObj() was fetched outside of the loop.
    
    (regression from commit c799de145f7e289f31e3669646e5bd12814e6c5e
     and commit 533a998e540b0f04068c876dde0e74adc3f79c93)
