 Fix a case where c$resp$size is misrepresented.  Addresses #730.

 That field is based on TCP sequence numbers and on seeing a SYN followed
 by a failed RST injection response, the initial sequence number tracked
 the value in the injection (most likely zero) instead of value in
 subsequent SYN response.  This could make c$resp$size be set to large
 values when it's not really.

 Also removed some dead code paths.
