drm/amdgpu: fix suspend/resume hang regression
[ Upstream commit f1ef17011c765495c876fa75435e59eecfdc1ee4 ]
Regression has been reported that suspend/resume may hang with
the previous vm ready check commit.
So bring back the evicted list check as a temp fix.
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1922
Fixes: c1a66c3bc425 ("drm/amdgpu: check vm ready by amdgpu_vm->evicting flag")
