4.9-stable review patch. If anyone has any objections, please let me know.

commit cef75036c40408ba3bc308bcb00a3d440da713fc upstream.
This is an extension of Commit 7c20d213dd3c ("drm/vmwgfx: Work around mode set failure in 2D VMs")
With Wayland desktop and atomic mode set, during the mode setting process there is a moment when two framebuffer sized surfaces are being pinned. This was not an issue with Xorg.
Since this only happens during a mode change, there should be no performance impact by increasing allowable mem_size.
