David Howells e44150157f afs: Add missing afs_put_cell()
afs_alloc_volume() needs to release the cell ref it obtained in the case of
an error.  Fix this by adding an afs_put_cell() call into the error path.

This can triggered when a lookup for a cell in a dynamic root or an
autocell mount returns an error whilst trying to look up the server (such
as ENOMEDIUM).  This results in an assertion failure oops when the module
is unloaded due to outstanding refs on a cell record.

Fixes: d2ddc776a4 ("afs: Overhaul volume and server record caching and fileserver rotation")

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

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
