tdf#91602: sw: prevent recursive layout crash

SwCrsrShell::UpdateCrsr() calls SwTextFrm::GetCharRect(), which does
layout.  It happens that a SdrObject is moved around during layout,
which calls SwDrawContact::Changed(), which believes that there is
no layout active because there is no SwLayAction and
ViewShell::EndAction() has already been called, so we get recursive
layout-in-layout action.
