res_pjsip_pubsub: destroy old subscriptions on RLS update using serializer

Set termination state to old subscriptions to immediately stop
sending NOTIFY messages on exten/device state changes.

Fix a data-race on RLS update.
While destroying old subscriptions, they can be used by exten/device
state changes. Thus, we need to add a task into serializer of
subscription tree to destroy old subscriptions.
