Description
===========
The error handling around swap_volume is missing the following failure when calling virDomainGetBlockJobInfo() after the entire device is detached by QEMU (?) after it encounters a failure during the block copy job that at first pauses and then somehow resumes:

Expected result
===============
swap_volume at least fails correctly leaving the original device attached.
Actual result
=============
swap_volume fails and the original device appears detached from the device.
Environment
===========
1. Exact version of OpenStack you are running. See the following
list for all releases: http://docs.openstack.org/releases/
master
2. Which hypervisor did you use?
(For example: Libvirt + KVM, Libvirt + XEN, Hyper-V, PowerKVM, ...)
What's the version of that?
libvirt + QEMU (no KVM in the gate)
2. Which storage type did you use?
(For example: Ceph, LVM, GPFS, ...)
What's the version of that?
images_type=default=qcow2
3. Which networking type did you use?
(For example: nova-network, Neutron with OpenVSwitch, ...)
