Some bus_dma(9) fixes for Xen:
- Attempt to gracefully recover from a failed decrease_reservation or
  increase_reservation, by avoiding physical memory loss.
- always store a machine address in ds_addr; this avoids some mistakes
  where machine address would in some case be freed at physical address, or
  mapped as physical address.
Wrap some printfs in #ifdef DEBUG, as we should not leak memory any more when
bus_dma memory allocation fails.
