RESPONDER: Fix segfault in sss_packet_send()
There are several places (all error-handling) where sss_cmd_done() is called with no response packet created. As a short-term solution, we need to check whether the packet is NULL and simply return EINVAL. client_send() (the consumer) will then forcibly disconnect the client (which will return PAM_SYSTEM_ERR to the client).
