6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher alexander.deucher@amd.com
This reverts commit 71598a5a7797f0052aaa7bcff0b8d4b8f20f1441 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.
