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).
