    Fix for status-set race - related to bug 1588462

    This change fixes the obvious race for a status_set() between
    check_optional_interfaces() and assess_status() as the later calls the former
    which calls status_set(), returns the status, which is then potentially set
    again by the assess_status() function. This cleans up the code so that only a
    single status_set() is performed when calling assess_status().
