[ Upstream commit789e1e10f2] Currently, we shut down the filecache before trying to clean up the stateids that depend on it. This leads to the kernel trying to free an nfsd_file twice, and a refcount overput on the nf_mark. Change the shutdown procedure to tear down all of the stateids prior to shutting down the filecache.

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 Restructured Text 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.
