It seems that you are getting errors reported while running kernel threads. This fix avoids
pointlessly adding "task_work" that will never be processed because kernel threads never
return to user mode.
But maybe something else needs to be done? The code was, and with this fix still is,
taking no action for the error. That doesn't seem right.
Are you injecting errors to create this scenario? What does your test do?
