Haiyue Wang befd9a71d8 fuse: fix runtime warning on truncate_folio_batch_exceptionals() 
The WARN_ON_ONCE is introduced on truncate_folio_batch_exceptionals() to
capture whether the filesystem has removed all DAX entries or not.

And the fix has been applied on the filesystem xfs and ext4 by the commit
0e2f80afcf ("fs/dax: ensure all pages are idle prior to filesystem
unmount").

Apply the missed fix on filesystem fuse to fix the runtime warning:

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
