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.
