drm: Use default dma_fence hooks where possible for null syncobj
Both the .enable_signaling and .release of the null syncobj fence can be replaced by the default callbacks for a small reduction in code size. In particular the default callback for .release was changed in commite28bd101ae
("drm: rename null fence to stub fence in syncobj v2") which neglected its RCU protection. Fixes:e28bd101ae
