Pushed to drm-misc-next

Attached a patch. Give it a try please, I tested it on my side and tried to generate the right conditions to trigger this code path by repeatedly submitting commands while issuing GPU reset to stop the scheduler and then killing command submissions process in the middle. But for some reason looks like the job_queue was always empty already at the time of entity kill.

It was trivial to trigger with the stress utility I've hacked together:

amdgpu_stress -b v 1g -b g 1g -c 1 2 1g 1k

Then while it is copying just cntrl+c to kill it.

The patch itself is:
