connect: 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. Fixes #794
