    use already loaded BDM in instance.<action> (2)

    I8849ae0f54605e003d5b294ca3d66dcef89d7d27 made it possible for
    _get_instance_block_device_info to take a BDM parameter instead of
    loading the BDM from the db. This allow us to load the BDM a bit
    earlier in the call chain and pass that BDM to the notification calls
    too.

    The remaining calls of the notify_about_instance_action does not have
    the BDM loaded already.
