Description of problem:
After a failure in snapshot creation (during createVolume task), vdsm get the request from engine to perform roll-back and start a deleteImage task. This task gets stuck forever on vdsm. User has to stop and clean it manually. 

Version-Release number of selected component (if applicable):
vdsm-4.13.0-0.2.beta1.el6ev.x86_64
libvirt-0.10.2-29.el6.x86_64
rhevm-3.3.0-0.25.beta1.el6ev.noarch

How reproducible:
100%

Steps to Reproduce:
On a block pool:
- create a vm with 2 disks and run it
- create snapshot to the vm (with 'save memory' check-box checked) and during the createVolume task, restart vdsm service

Actual results:
vdsm gets the request from engine to perform roll-back and delete the image.
deleteImage task starts on vdsm and it won't end forever
