drm/ttm: Reorder sys manager cleanup step
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().
