I found that when a connection is re-used over easies that
had CURLOPT_CONNECT_ONLY set, a curl_easy_getinfo() for
CURLINFO_LASTSOCKET fails (returning -1) for the subsequent easy.

curl_test.cpp is a small program illustrating the issue giving
curl_connectonly.out as output. When omitting CURLOPT_CONNECT_ONLY, i get
curl_perform.out, where the socket is returned correctly.

Can you reproduce it ?
