It would be even better if you can show me the return code of
bus_dmamap_load(9). If the error code is not ENOMEM it requires
more bus_dma(9) clean up(bfe(4) needs lots of bus_dma(9) fixing
and I had no time so far.)
Since the caller of bfe_list_newbuf() expects 0 or ENOBUFS it would
be even better to return ENOBUFS for failure case instead of
returning error code of bus_dmamap_load(9).
