The code to figure out how many pages to shrink the pool ends up capping the 'count' at _manager->options.max_size - which is OK. Except that the 'count' is also used when accounting for how many pages are recycled - which we end up with the invalid values. This fixes it by using a different value for the amount of pages to shrink. On top of that we would free the cached page pool - which is nonsense as they are deleted from the pool - so there are no free pages in that pool.. Also we also missed the opportunity to batch the amount of pages to free (similar to how ttm_page_alloc.c does it). This reintroduces the code that was lost during rebasing.
