- Fixed CURLINFO_PRIMARY_IP: When libcurl created a connection to host A then

the app re-used the handle to do a connection to host B and then again
  re-used the handle to host A, it would not update the info with host A's IP
  address (due to the connection being re-used) but it would instead report
  the info from host B.
