Colin Ian King 32d57c0c06 cifs: fix memory leak of pneg_inbuf on -EOPNOTSUPP ioctl case
commit 210782038b upstream.

Currently in the case where SMB2_ioctl returns the -EOPNOTSUPP error
there is a memory leak of pneg_inbuf. Fix this by returning via
the out_free_inbuf exit path that will perform the relevant kfree.

Addresses-Coverity: ("Resource leak")
Fixes: 969ae8e8d4 ("cifs: Accept validate negotiate if server return NT_STATUS_NOT_SUPPORTED")

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.
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.
