This is in preparation for the removal of find_get_pages_range_tag(). This change removes 7 calls to compound_head(). Also modified f2fs_all_cluster_page_ready to take in a folio_batch instead of pagevec. This does NOT support large folios. The function currently only utilizes folios of size 1 so this shouldn't cause any issues right now.
