    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.

    NOTE(lyarwood): Test conflict caused by the mox to mock migration in
    I8d4d8a. As a result test_rebuild_on_remote_host_with_volumes remains a
    mox based test.
