[ Upstream commit 53139b3f9998ea07289e7b70b909fea2264a0de9 ]
There is an error path in igt_ppgtt_alloc(), which leads
to ww object being passed down to i915_gem_ww_ctx_fini() without
initialization. Correct that by only putting ppgtt->vm and
returning early.

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.
