When unload amdgpu driver we use sdma to evict vram but there is no irq process after sdma completed work which raises that waiting for the fence costs 2s which will trigger VFLR under SRIOV and at last make unload driver failed.The reason is that the shutdown varible in adev is set to true before evict vram, it cause ISR directly return without processing.Therefore, we need set the varible after evict vram.
