<pre>This reproducible all the time with Dota2 starting a benchmark with 1920x1080
and Vulkan using Phoronix test suite.
Starting the benchmark makes the machine freeze and you just can hit the reset
button.
I also experienced the freeze with Shadow of Mordor but not all the time.

drm/scheduler: add NULL pointer check for run queue (v2)
To check rq pointer before adding entity into it.
That avoids NULL pointer access in some case.
v2: move the check to caller
