> The function pubsub_on_rx_publish_request incorrectly uses of AST_SCHED_REPLACE_UNREF.
> The AST_SCHED_REPLACE_UNREF should unref old '_data'.
> Because of this, there may be a double unref of variable 'publication' when ast_sched_del is unsuccessful that leads to use after free of the 'publication' in publish_expire.
