Karolina StolarekandGreg Kroah-Hartman e39440c326 drm/ttm: Reorder sys manager cleanup step ...

[ Upstream commit 3b401e30c2 ]

With the current cleanup flow, we could trigger a NULL pointer
dereference if there is a delayed destruction of a BO with a
system resource that gets executed on drain_workqueue() call,
as we attempt to free a resource using an already released
resource manager.

Remove the device from the device list and drain its workqueue
before releasing the system domain manager in ttm_device_fini().
