[ Upstream commit 7270e8957eb9aacf5914605d04865f3829a14bce ]
[why] In rmmod procedure, kfd sends cp a dequeue request, but the request does not get response, then an error message "cp queue pipe 4 queue 0 preemption failed" printed.
[how] Performing kfd suspending after disabling gfxoff can fix it.
