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.
