Commit 0e2f80afcfa6("fs/dax: ensure all pages are idle prior to
filesystem unmount") introduced the WARN_ON_ONCE to capture whether
the filesystem has removed all DAX entries or not and applied the
fix to xfs and ext4.
Apply the missed fix on erofs to fix the runtime warning:

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.
