This is an existing but formerly not reported GPU hang driver issue
exhibited by the test, not a regression.  The issue needs to be fixed
in the driver for the test to succeed.  As one can see from CI reports,
the test succesfuly recovers from that condition and subsequent tests
are not affected.

This is a known driver issue, already reported by igt@device
_reset@unbind-reset-rebind.  This test shows clearly that the issue has
nothing to do with device reset, only with driver unbind-rebind cycle. 
The driver needs to be fixed for the kernel warning not be triggered
and the tests succeed.

This issue seems hardly related to the igt@core_hotunplug test which is
the only one modified by the patch series.  Even if popped up in the
same CI run as a GPU hang caused by igt@core_hotunplug@hotrebind-
lateclose, at least one subsequent test which depended on a healthy GPU
(igt@gem_exec_fence@syncobj-timeline-export) was run with success after
the igt@core_hotunplug@hotrebind-lateclos recovered successfully from
the GPU hang and before this failure occurred.  Then I think we can't
blame core_hotunplug for this failure and we should treat the report of
this issue being a regression introduced by this patch series as a
false positive.

Even if this issue occurred in the same CI run as the core_hotunplug
was planned to be executed, it happened earlier and the run was
aborted.  Then, there is no connection between both, so no regression
caused by this patch seriesa.

I think the *bind* subtests in their current shape are perfectly ready
for inclusion in CI runs.
