[PATCH] drm/amdgpu: fix suspend/resume hang regression

[Qiang Yu]

Regression has been reported that suspend/resume may hang with
the previous vm ready check commit:
https://gitlab.freedesktop.org/drm/amd/-/issues/1915#note_1278198

So bring back the evicted list check as a temp fix.

Fixes: cc8dd2cc1a97 ("drm/amdgpu: check vm ready by amdgpu_vm->evicting flag")
