[PATCH 5.7 197/204] drm/amdgpu: fix ordering of psp suspend

From: Alex Deucher <alexdeucher@gmail.com>

The ordering of psp_tmr_terminate() and psp_asd_unload()
got reversed when the patches were applied to stable.

This patch does not exist in Linus' tree because the ordering
is correct there. It got reversed when the patches were applied
to stable. This patch is for stable only.

Fixes: 22ff658396b446 ("drm/amdgpu: asd function needs to be unloaded in suspend phase")
Fixes: 2c41c968c6f648 ("drm/amdgpu: add TMR destory function for psp")
