P2PS: Notify D-Bus about removal of a stale persistent group

Browse source 
During P2PS PD Request processing wpa_supplicant removes stale
persistent groups, but it did not notify D-Bus to unregister object.
This can result in leaving behind objects pointing to freed memory and
memory leaks. Sometime it can cause a crash in wpa_config_get_all()
function and DBUS_ERROR_OBJECT_PATH_IN_USE errors.

Fix this by adding the missed notification to D-Bus code to unregister
the object.
