Use the correct attachment id for multiattach.

A volume attached to multiple servers has multiple attachment structures
that are distinguished by their "attachment_id" field, not the "id" one.
So when setting up a waiter watching for an attachment being removed,
the "attachment_id" field must be passed. Thus, when attaching a volume,
it is necessary to wait until the attachment shows up in the volume's
data and then use the "attachment_id" field of that record to pass to
the waiter invoked at tear-down time.
