gpu: nvgpu: gk20a: free syncpt if last submit is complete
In channel_update(), we detect if channel is idle and if it is
idle then we free the syncpt. We do not free the syncpt if WFI is
scheduled on some other path.
Instead of checking for WFI, we can check if last submit is complete
or not (it can be WFI as well) and if last submit is complete then
we can free the syncpt.
Locking mechanism using submit lock will take care that syncpt is
kept alive until last submit or WFI completes
