gpu: nvgpu: Update channel on semaphore release

Browse Source 
When using semaphore based channel synchronization, a semaphore release
may mean that a job has completed. Call gk20a_channel_update from
gk20a_channel_semaphore_wakeup to check if there are memory refs to
release or sync timelines to signal.
