DPDK intr thread is designed that it can't unregister the src
callback in this callback handler. So I think we can't detach
the PCI device in the hotremove callback as it needs to unregister
the VFIO notification callback which will be not successful
but it still can free the device. So at the next req notification
in the handler function, we meet the freed device.
Fix#994
