core: simplify DHCP cleanup

Browse source 
dhcp6_cleanup() frees priv->dhcp6_ip6_config so dispose() doesn't need
to do that.  Also use g_clear_object() when appropriate.

Lastly, notify that the DHCP4/6 config objects have changed *after*
clearing them, so that the PropertiesChanged signal is emitted with a
blank path to indicate the object is gone.  Previously the PC signal
would have been emitted with the valid path of the DHCP4/6 config object,
but the object would already be dead.
