    smart_pkt: treat empty packet lines as error
    
    The Git protocol does not specify what should happen in the case
    of an empty packet line (that is a packet line "0004"). We
    currently indicate success, but do not return a packet in the
    case where we hit an empty line. The smart protocol was not
    prepared to handle such packets in all cases, though, resulting
    in a `NULL` pointer dereference.
    
    Fix the issue by returning an error instead. As such kind of
    packets is not even specified by upstream, this is the right
    thing to do.
