drm/vmwgfx: Fix Host-Backed userspace on Guest-Backed kernel

Browse source

[ Upstream commit 7872997c04 ]

Running 3D applications with SVGA_FORCE_HOST_BACKED=1 or using an
ancient version of mesa was broken because the buffer was pinned in
VMW_BO_DOMAIN_SYS and could not be moved to VMW_BO_DOMAIN_MOB during
validation.

The compat_shader buffer should not pinned.
