If v9fs_fid_lookup_with_uid() fails then "fid" is not initialized.
The v9fs_fid_lookup_with_uid() can't return NULL. If it returns an
error pointer then we can still pass that to clone_fid() and it will
return the error pointer back again.
Fixes: 6636b6dcc3 ("9p: add refcount to p9_fid struct")

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.
