The page pool uses an internal data structure, ion_page_pool_item, for
wrapping pooled pages and constructing a list. As the struct page
already provides ways for doing exactly the same thing, we do not need
to reinvent the wheel. This commit removes the data structure and slab
allocations for it.

ion_page_pool_total() returns the total number of pages in the pool.
Depending on the argument passed, it counts highmem pages in or not.
This commit simplifies the code lines for better readability.
