gpu: nvgpu: fix semaphore wakeup logic
Currently, when we receive a semaphore wakeup interrupt,
we call the channel_update callback, which schedules
deferred job clean-up.
For deterministic channels, we don't allow semaphore-backed
syncs anyways. That means for these channels, if we get a
semaphore wakeup interrupt, it must be for a userspace-managed
semaphore. In this case, there is no need to call into the
channel_update callback. So for deterministic channels, we
skip this.
