drm/amdgpu: fix tear down order in amdgpu_vm_pt_free
When freeing PD/PT with shadows it can happen that the shadow
destruction races with detaching the PD/PT from the VM causing a NULL
pointer dereference in the invalidation code.
Fix this by detaching the the PD/PT from the VM first and then
freeing the shadow instead.
