  lxccontainer.c: check lxc_conf before referance haltsignal

If we start container with rcfile(see comments in lxc_start.c), it
is possible that we have no config file in /usr/local/var/lib/lxc.
So when we try lxc_stop, lxc_container_new will not load any config
so we'll get c->lxc_conf = NULL.

In that case, we'll get Segmentation fault in lxcapi_shutdown, a
simple check would fix this.
