dma-buf: Update kerneldoc for sync_file_create
commit 24a367348a017555f982a9ee137070a7a821fa97 upstream.
This was missed when adding a dma_fence_get call. While at it also
remove the kerneldoc for the static inline helper - no point
documenting internals down to every detail.
Fixes: 30cd85dd6edc ("dma-buf/sync_file: hold reference to fence when creating sync_file")
