Description of problem:
2 SD, 1 host, 2 vms with disks
1 vm with snapshot.
When attaching snapshot disk of first vm to second vm (backup api -, and trying to migrate second vm disks, operation fails with message :
"Failed to complete snapshot 'Auto-generated for Live Storage Migration' creation for VM 'vm_1'."

The 'Auto-generated for Live Storage Migration' snapshot is still in snapshot list of the second vm and cannot be deleted.

From vdsm side: Thread-42492::DEBUG::2014-02-17 10:09:50,182::
return vmSnapshot with {'status': {'message': 'Action not permitted on a VM with transient disks', 'code': 59}}

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Attach snapshot disk of first vm to second vm
2. Move second vm disk to other storage domain

Actual results:
New snapshot 'Auto-generated for Live Storage Migration' is created and ERROR message appears: "Failed to complete snapshot 'Auto-generated for Live Storage Migration' creation for VM 'vm_1'." this snapshot isn't deleted after the error message

Expected results:
A message that alerts the user that this operation is invalid
