6.13-stable review patch. If anyone has any objections, please let me know.

commit de70981f295e7eab86325db3bf349fa676f16c42 upstream.
When a queue is stopped using the ndo queue API, before destroying its page pool, the associated NAPI instance needs to be unlinked to avoid warnings.
Handle this by calling page_pool_disable_direct_recycling() when stopping a queue.
