Felix Kuehling 705d85f68a drm/amdgpu: Sync with VM root BO when switching VM to CPU update mode 
[ Upstream commit 90ca78deb004abe75b5024968a199acb96bb70f9 ]

This fixes an intermittent bug where a root PD clear operation still in
progress could overwrite a PDE update done by the CPU, resulting in a
VM fault.
