Convert to use folios throughout. This is in preparation for the removal for find_get_pages_contig(). Now also supports large folios. The initial version of this function set the page_address to be returned after finishing all the checks. Since folio_batches have a maximum of 15 folios, the function had to be modified to support getting and checking up to lpages, 15 pages at a time while still returning the initial page address. Now the function sets ret as soon as the first batch arrives, and updates it only if a check fails. The physical adjacency check utilizes the page frame numbers. The page frame number of each folio must be nr_pages away from the first folio.
