Revert previous diff decrementing bcstats.numbufpages here. This function

does not do what it purports to do, it shrinks mapping, not allocation, as
the pages have already been given away to other buffers. This also renames
the function to make this a little more obvious

and art should not name funcitons

ok thib@, art@
