drm/amdgpu: Let KFD sync with VM fences

Browse source

[ Upstream commit ec9ba4821f ]

Change the rules for amdgpu_sync_resv to let KFD synchronize with VM
fences on page table reservations. This fixes intermittent memory
corruption after evictions when using amdgpu_vm_handle_moved to update
page tables for VM mappings managed through render nodes.
