[ Upstream commit 510a405d945bc985abc513fafe45890cac34fafa ]
Unconditionally hide device pm latency tolerance when uninitializing the controller to ensure all qos resources are released so that we're not leaking this memory. This is safe to call if none were allocated in the first place, or were previously freed.
