Cinder and Nova logs

Description of problem: While clearing a failed Cinder volume migrate error state, Cinder list still shows volume as attached, yet nova detach says volume isn't attached. This might end-up being a Nova attach/detach bug. 

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

How reproducible:

Steps to Reproduce:
1. Configure a dual cinder system 
2. Create a volume, attach it to an instance
3. Cinder migrate the volume from one backend to the other.    (cause it to fail, in my case I think being attached caused migration error, I suspect causing migration to fail can also be done if there is insufficient free space on target backend.  
4. Cinder list - see migration error state
5. Cinder reset-state [vol_id] --migration..
6. Check cinder status of volume - still attached
7. Try nova volume-detach -> hit bug reports volume is already detached. 

Actual results:
Failed to detach a volume but Cinder still reports it as attached. 

Expected results:
Cinder reset-state of a detached volume, should be synced with Nova volume status.
