Subject: drm/vmwgfx: Fix Ubuntu 17.10 Wayland black screen issue

From: Sinclair Yeh <[email protected]>

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.
