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