This series of patches modify the order of resetting/deassigning
device.

I modify the order of resetting/deassigning device like below.

  When guest OS shutdowns or a device is hotremoved.
   1. Xend resets devices.
   2. Xend deassigns devices.

Because if devices are deassigned before the reset, dom0 memory may be
broken by DMA

Thanks,
