BUG/MEDIUM: checks: Don't attempt to receive data if we already subscribed.

tcpcheck_main() might be called while we already attempted to subscribe, and
failed. There's no point in trying to call rcv_buf() again, and failing
would lead to us trying to subscribe again, which is not allowed.

This should be backported to 2.0 and 1.9.
