[Chen Fan <chen.fan.fnst@cn.fujitsu.com>]

For now, for vfio pci passthough devices when qemu receives
an error from host aer report, there just terminate the guest,
but usually user want to know what error occurred but stop the
guest, so this patch add aer capability support for vfio device,
and pass the error to guest, and have guest driver to recover
from the error.
