res_pjsip_pubsub: segfault in function publish_expire

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.
