Revert "drm/amdgpu: Avoid extra evict-restore process."

Browse Source 
This reverts commit a3201e3b7c which is
commit 1f02f2044bda1db1fd995bc35961ab075fa7b5a2 upstream.

This commit introduced a regression, however the fix for the regression:
aa5fc4362fac ("drm/amdgpu: fix task hang from failed job submission
during process kill") depends on things not yet present in 6.12.y and
older kernels.  Since this commit is more of an optimization, just
revert it for 6.12.y and older stable kernels.
