[0/2] btrfs: allow creating inline data extents for sector size < page size case

Message

There are two features disabled when sector size < page size (subpage) is
allowed for btrfs:

- Inline data extent creation
- Sector perfect compressed write

Both share one critical technical problem, that inline or async
submission all unlock the whole page.

Thankfully the major technical blockage is already solved with the
recent sector perfect compressed write support for subpage cases.

So there is no need to disable inline data extent creation either.
Yes, there are cases we can mixing inline and regular data extents, but
that's also the case when page size == sector size, so it's not a show
stopper.

The first patch is to fix a harmless bug that is only affecting subpage
cases.
The second one enables the inline data extent creation for subpage
cases.

  btrfs: fix the qgroup data free range for inline data extents
  btrfs: allow inline data extents creation if sector size < page size
