Lee Yarwood 1252588d4e api: Reject volume attach requests when an active bdm exists 
When attaching volumes to instances Nova has previously relied on checks
carried out by c-api to ensure that a single non-multiattach volume is
not attached to multiple instances at once. While this works well in
most cases it does not handle PEBKAC issues when admins reset the state
of a volume to available, allowing users to request that Nova attach the
volume to another instance.

This change aims to address this by including a simple check in the
attach flow for non-multiattach volumes ensuring that there are no
existing active block device mapping records for the volume already
present within Nova.

Closes-Bug: #1908075
