Account for possible NULL pointer when we receive a 408 in response to a REGISTER

It may be that by the time we receive a reply to a REGISTER request, the attempt has
timed out and thus the registry structure pointed to by the corresponding sip_pvt has
gone away. This situation was handled properly for a 200 OK response, but the 408
case assumed that the sip_registry struct was non-NULL, thus potentially causing a crash

This commit fixes this assumption and prints out a message to the console if we should
receive a late 408 response to a REGISTER
