Lee Yarwood fdf3328107 compute: Skip driver detach calls for non local instances 
Only call for a driver detach from a volume if the instance is currently
associated with the local compute host. This avoids potential virt
driver and volume backend issues when attempting to disconnect from
volumes that have never been connected to from the current host.

Closes-Bug: #1583284
