agent: Don't crash when no agent was registered on exit
If the user never registered an agent, agent_sender and agent_path
are NULL. D-Bus does not handle this gracefully, instead it kills
ConnMan. So let's skip the D-Bus part in this case.
connmand[4271]: src/agent.c:connman_agent_driver_unregister() Sending release to (null) path (null) iface net.connman.Agent
process 4271: arguments to dbus_message_new_method_call() were incorrect, assertion "path != NULL" failed in file dbus-message.c line 1198.
This is normally a bug in some application using the D-Bus library.
D-Bus not built with -rdynamic so unable to print a backtrace
