Add page_pool_update_nid() to be called by page pool consumers when they detect numa node changes. It will update the page pool nid value to start allocating from the new effective numa node. This is to mitigate page pool allocating pages from a wrong numa node, where the pool was originally allocated, and holding on to pages that belong to a different numa node, which causes performance degradation. For pages that are already being consumed and could be returned to the pool by the consumer, in next patch we will add a check per page to avoid recycling them back to the pool and return them to the page allocator.
