drm/amdgpu/sriov Stop data exchange for wholegpu reset
[Why]
When host trigger a whole gpu reset, guest will keep
waiting till host finish reset. But there's a work
queue in guest exchanging data between vf&pf which need
to access frame buffer. During whole gpu reset, frame
buffer is not accessable, and this causes the call trace.
[How]
After vf get reset notification from pf, stop data exchange.
