    afc: Add guards against the operation mode not being set
    
    We usually did:
    if mode == AFC; <foo> else <bar>
    
    To guard against the mode not actually being HouseArrest in the else
    branch, change this to:
    if mode == AFC; <foo> else if mode == HOUSE_ARREST ; <bar> ; else ; <baz>
