    Fix use-after-free on a network error.
    
    When any BPP calls ssh_remote_error or ssh_remote_eof, it triggers an
    immediate cleanup of the BPP itself - so on return from one of those
    functions we should avoid going straight to the crFinish macro,
    because that will write to s->crState, which no longer exists.
