- Bug #2218480 (http://curl.haxx.se/bug/view.cgi?id=2218480) pointed out a

problem with my CURLINFO_PRIMARY_IP fix from October 7th that caused a NULL
  pointer read. I also took the opportunity to clean up this logic (storing of
  the connection's IP address) somewhat as we had it stored in two different
  places and ways previously and they are now unified.
