btrfs: make page Ordered bit to be subpage compatible

Browse source

This involves the following modification:

- Ordered extent creation
  This is done in process_one_page(), now PAGE_SET_ORDERED will call
  subpage helper to do the work.

- endio functions
  This is done in btrfs_mark_ordered_io_finished().

- btrfs_invalidatepage()

- btrfs_cleanup_ordered_extents()
  Use the subpage page helper, and add an extra branch to exit if the
  locked page have covered the full range.

Now the usage of page Ordered flag for ordered extent accounting is fully
subpage compatible.
