  Allow bus_dmamap_load() to pass ENOMEM back to the caller.  This puts it into
  conformance with the mbuf and uio load routines.  ENOMEM can only happen
  with BUS_DMA_NOWAIT is passed in, thus the deferals are disabled.  I don't
  like doing this, but fixing this fixes assumptions in other important drivers,
  which is a net benefit for now.
