  SVN rev 188403 on 2009-02-09 18:03:31Z by cognet
  
  The bounce zone sees its page number increased if multiple dma maps use it in
  the same dma tag. However, it can happen multiple dma tags share the same
  bounce zone too, so add a per-bounce zone map counter, and check it instead of
  the dma tag map counter, to know if we have to alloc more pages.
