Code Issues Proposed changes

Cinder duplicated volume sync due to potential time window issue 

From PBC, the customer encounter below error:

1. Create a volume in ICM
2. Update PowerVC UUID in cinder volume metadata, in the mean time,
PowerVC volume created, end event comes.
3. Check if PowerVC UUID set in volume metadata, but there is
Time window issue here, sometimes db update not reflect
immediately, so no PVC UUID found , and create a duplicated
volume by mistake.
