Dave Airlie a1e80a33bf nouveau/vmm: don't set addr on the fail path to avoid warning
commit cacea81390fd8c8c85404e5eb2adeb83d87a912e upstream.

nvif_vmm_put gets called if addr is set, but if the allocation
fails we don't need to call put, otherwise we get a warning like

README

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.
