nvservice: add a lock around NvHostEvent and remove release fence on SFv2 (#1197)

Browse Source 
* nvservice: add a lock to NvHostEvent

* Disable surface flinger release fence and readd infinite timeout

* FenceAction: Add a timeout of 1 seconds as this shouldn't wait forever anyuway

* surfaceflinger: remove leftovers from the release fence

* Don't allow infinite timeout on syncpoint while printing all timeout for better debugging
