Subject: drm/amdgpu: fix unload driver issue for virtual display
From: Xiangliang Yu <Xiangliang.Yu@xxxxxxx>
[ Upstream commit 3a1d19a29670aa7eb58576a31883d0aa9fb77549 ]
Virtual display doesn't allocate amdgpu_encoder when initializing,
so will get invaild pointer if try to free amdgpu_encoder when
unloading driver.
