fuse: use iomap helper to mark folio uptodate
When fuse enables large folios, a large folio will be backed by
iomap_folio_state that keeps track of uptodate and dirty state in an
internal bitmap.
Fuse writethrough and notify store paths currently set folio uptodate
state with folio_mark_uptodate(), which touches only the folio-level
flag, but on an iomap-backed folio, that leaves the uptodate bitmap out
of sync.
Use the iomap_folio_mark_uptodate() helper to update both the folio
uptodate state and the iomap uptodate bitmap.
