    use already loaded BDM in instance.<action>

    In I18e7483ec9a484a660e1d306fdc0986e1d5f952b BDM was added to the instance
    notifications. In general to add BDM to the payload an exta DB query is
    needed. However in some places the BDM is already separately before the
    notify_about_instance_action is called to send the notification. In this cases
    loading the BDM again is unnecessary as the already loaded BDM can be reused.

    This patch makes sure that notify_about_instance_action is called with the
    already loaded BDM. There will be subsequent patches to do the same with
    other notify calls.
