Subject: [PATCH] Fix invalid "Network is unreachable" errors

Sometimes, in systems with both ipv4 and ipv6 addresses but where the
network doesn't support ipv6, Curl_is_connected returns an error
(intermittently) even if the ipv4 socket connects successfully.

This happens because there's a for-loop that iterates on the sockets
but the error variable is not resetted when the ipv4 is checked and
is ok.

This patch fixes this problem by setting error to 0 when checking the
second socket and not having a result yet.
