Description of problem:
If a storage domain contains an image of RAM snapshot and the domain is in inactive state, preview snapshot to the VM is allowed. 

Version-Release number of selected component (if applicable):
rhevm-3.4.0-0.12.beta2.el6ev.noarch
vdsm-4.14.5-0.2.beta2.el6ev.x86_64

How reproducible:
Always

Steps to Reproduce:
On a DC (local/shared) with more than 1 storage domains:
1. Create a VM and run it
2. Create snapshot to the VM with RAM saved
3. Shut down the VM
4. Put the storage domain where the RAM image was saved to in maintenance
5. Try to preview the snapshot with the RAM 


Actual results:
Snapshot preview with RAM is allowed, even though the RAM image cannot be accessed since the storage domain where it is located is inactive.
When starting this VM with the snapshot pre-viewed, the RAM Memory restore fails.

Expected results:
If RAM memory image cannot be accessed, snapshot preview with RAM memory should not be allowed. It should be the same behaviour as previewing a snapshot which its data disk cannot be accessed.
