    Don't warn about not sending a socks reply if we get a write error
    
    If we get a write error on a SOCKS connection, we can't send a
    SOCKS reply, now can we?
    
    This bug has been here since 36baf7219, where we added the "hey, I'm
    closing an AP connection but I haven't finished the socks
    handshake!" message.  It's bug 8427.
