sw: fix use-after-free when moving multiple tables to a previous page
Regression from commit e4da634b983052f300cd0e9b2bbaa60eb02c1b28 (sw: fix
moving more than 20 table frames to a previous page, 2020-03-30), asan
found a heap-use-after-free during CppunitTest_sw_ooxmlexport5
CPPUNIT_TEST_NAME=testOldComplexMergeTableInTable, the follow frame is
deleted like this:
#1 in SwTabFrame::~SwTabFrame() at sw/source/core/layout/tabfrm.cxx:145:1 (instdir/program/libswlo.so +0xec98ba5)
#2 in SwFrame::DestroyFrame(SwFrame*) at sw/source/core/layout/ssfrm.cxx:389:9 (instdir/program/libswlo.so +0xec8495f)
#3 in SwTabFrame::Join() at sw/source/core/layout/tabfrm.cxx:1390:9 (instdir/program/libswlo.so +0xecb6088)
#4 in SwTabFrame::MakeAll(OutputDevice*) at sw/source/core/layout/tabfrm.cxx:1865:9 (instdir/program/libswlo.so +0xecbc1f6)
#5 in SwFrame::PrepareMake(OutputDevice*) at sw/source/core/layout/calcmove.cxx:370:5 (instdir/program/libswlo.so +0xe519919)
#6 in SwFrame::Calc(OutputDevice*) const at sw/source/core/layout/trvlfrm.cxx:1789:37 (instdir/program/libswlo.so +0xed8424e)
#7 in SwLayAction::FormatLayoutTab(SwTabFrame*, bool) at sw/source/core/layout/layact.cxx:1485:15 (instdir/program/libswlo.so +0xe897ea9)
Fix the problem by not moving multiple tables to a previous page in one
iteration when the table is a follow one.
