Alex Waterman 7b8cbd2be3 gpu: nvgpu: Greatly simplify the semaphore detection ...

Greatly simplify and make more robust the gpu semaphore detection
in sync_fences. Instead of using a magic number use the parent
timeline of sync_pts.

This will also work with multi-GPU setups using nvgpu since the
timeline ops pointer will be the same across all instances of
nvgpu.
