gpu: nvgpu: wait ACK for FECS watchdog timeout

On Volta, nvgpu needs to wait for explicit ACK from CTXSW while
setting FECS watchdog timeoout

This is manual port of the fixes 4d7e5026e38528b88a4a168eca9a8b180475b368
and ad89436b03428a42e43042b6a849c15843fdebc4 on dev-main since clean
cherry-pick is not possible due to huge file and structure differences.

Bug 200603566
