Description of problem:
If storage domain remains locked and unable to remove datacenter (force remove also). After creating a master (iscsi) storage domain, ISO domain and another storage domain (unattached), storage was destroyed on the storage server. At this point removing the datacenter fails, causing  the master storage domain to become locked, and unable to remove using "force remove" either.

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


How reproducible:


Steps to Reproduce:
1. Create and attach master storage domain
2. Create and attach ISO domain
3. Create another storage domain
4. Try to activate the domain without attaching (using REST, fails obviously)
5. Remove storage from storage server 
6. Try to remove datacenter from GUI
  
Actual results:
Master storage domain becomes locked when removing it after the scenario is run

Expected results:
force remove should remove the datacenter
