sd-bus: if we receive an invalid dbus message, ignore and proceeed
    
    dbus-daemon might have a slightly different idea of what a valid msg is
    than us (for example regarding valid msg and field sizes). Let's hence
    try to proceed if we can and thus drop messages rather than fail the
    connection if we fail to validate a message.
    
    Hopefully the differences in what is considered valid are not visible
    for real-life usecases, but are specific to exploit attempts only.
