iomap: Rename iomap_page to iomap_folio_state and others

Browse source

struct iomap_page actually tracks per-block state of a folio.
Hence it make sense to rename some of these function names and data
structures for e.g.
1. struct iomap_page (iop) -> struct iomap_folio_state (ifs)
2. iomap_page_create() -> ifs_alloc()
3. iomap_page_release() -> ifs_free()
4. iomap_iop_set_range_uptodate() -> ifs_set_range_uptodate()
5. to_iomap_page() -> folio->private

Since in later patches we are also going to add per-block dirty state
tracking to iomap_folio_state. Hence this patch also renames "uptodate"
& "uptodate_lock" members of iomap_folio_state to "state" and"state_lock".

We don't really need to_iomap_page() function, instead directly open code
it as folio->private;
