    drm/xe/vm: prevent UAF in rebind_work_func()
    
    We flush the rebind worker during the vm close phase, however in places
    like preempt_fence_work_func() we seem to queue the rebind worker
    without first checking if the vm has already been closed.  The concern
    here is the vm being closed with the worker flushed, but then being
    rearmed later, which looks like potential uaf, since there is no actual
    refcounting to track the queued worker. To ensure this can't happen
    prevent queueing the rebind worker once the vm has been closed.
