drm/amdgpu: fix Null pointer dereference error in amdgpu_device_recover_vram

Browse source

Use the function of amdgpu_bo_vm_destroy to handle the resource release
of shadow bo. During the amdgpu_mes_self_test, shadow bo released, but
vmbo->shadow_list was not, which caused a null pointer reference error
in amdgpu_device_recover_vram when GPU reset.

Fixes: 6c032c37ac ("drm/amdgpu: Fix vram recover doesn't work after whole GPU reset (v2)")
