folio->private was set in order to get release_folio() callbacks.
Instead if we set address_space flags AS_RELEASE_ALWAYS, there is no
need to set EXTENT_FOLIO_PRIVATE on every folio->private.

These patches are posted so we don't face conflicts with iomap's
iomap_folio_state, which also resides in folio->private.

Changes since v1:
 - Incorporated Dave Sterba's comments

Goldwyn Rodrigues (2):
  btrfs: add mapping_set_release_always to inode's mapping
  btrfs: kill EXTENT_FOLIO_PRIVATE
