Subject: dma-buf: Update kerneldoc for sync_file_create

From: Daniel Vetter <daniel.vetter@ffwll.ch>

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.
