Description of problem:

after failure in preview of snapshot the snapshot appears as previewed in webadmin. 
checking the db snapshot table the status of the image is still IN_PREVIEW

this requires a manual intervention in db since we cannot create any snapshots, commit and undo will fail (since vdsm has rolled back). 

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

si4

How reproducible:

100%

Steps to Reproduce:
1. create 3 domains + vm with 3 disks on each domain
2. create a snapshot
3. put one domain in maintenance -> preview snaoshot
  
Actual results:

action will fail and eventually rollback
image will remain in webadmin as in preview 
db snapshot table shows that the image is in status IN_PREVIEW

Expected results:

we should change image status in db once we rollback

Could not reproduce in si6, getting the following message:
"    Cannot preview Snapshot. The relevant Storage Domain is inaccessible.
    -Please handle Storage Domain issues and retry the operation."
Can you please recheck?
