In commit 180253782038 ("drm/ttm: stop allocating dummy resources during BO creation")
ttm stopped allocating dummy resources but vmwgfx was never ported to
handle it. Make the driver treat null resources as initial creation and
port code to handle null resources in general.
Fixes kernel oops'es on boot with vmwgfx.

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.
