btrfs: subpage: make btrfs_is_subpage() check against a folio
To support large data folios, we can no longer assume every filemap
folio is page sized.
So btrfs_is_subpage() check must be done against a folio.
Thankfully for metadata folios, we have the full control and ensure a
large folio will not be large than nodesize, so
btrfs_meta_is_subpage() doesn't need this change.
