drm/amdgpu: fix wrong vram lost counter increment V2
Vram lost counter is wrongly increased by two during baco reset. V2: assumed vram lost for mode1 reset on all ASICs Signed-off-by: Evan Quan <evan.quan@amd.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
