Description of problem:
import of guest with shared disk and snapshot is failing

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


How reproducible:
everytime

Steps to Reproduce:
1, create 4 vms on sd_A:

vm_A with bootable disk disk_A and shared disk shared_1
vm_B with bootable disk disk_B and shared disk shared_1
vm_C with bootable disk disk_C and shared disk shared_2
vm_D with bootable disk disk_D and shared disk shared_2

2, create snapshot for the vms (in my case it was enough to create snapshot for the vm_A and vm_B)
3, put in maintenance & detach sd_A fro the datacenter
4, attach sd_A back to the datacenter or import it in new dc
5, import all 4 vms at once 

Actual results:
import fails for one of 4 vms with error below:

Expected results:
all guests will be imported
