tdf#71278 Revert both the previous cursor commit and the commit it fixed

The original commit was based on a misunderstanding. In fact, the call to
GetSalData()->getCursor() at the end of AquaSalFrame::getCurrentCursor()
already handles POINTER_NULL correctly, or at least in the same way as on
other platforms. The cursor in presentation mode disappears after 10
seconds - if this is to be changed, it should be changed for all platforms.
