Title:
If volume-attach API is failed, Block Device Mapping record will

Bug description:
I executed volume-attach API(nova V2 API) when RabbitMQ was down.
As result of above API execution, volume-attach API was failed and volume's
status is still available.
But, block device mapping record remains on nova DB.
This condition is inconsistency.
And, remained block device mapping record maybe cause some problems.
(I'm researching now.)
I used openstack juno-3.
