Modified Files:
	src/sys/arch/x86/include: bus_private.h

	src/sys/arch/xen/include: bus_private.h
	src/sys/arch/xen/x86: xen_bus_dma.c

Log Message:
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.
