Christian König 044e55b146 dma-buf: clarify dma_fence_add_callback documentation ...

That the caller doesn't need to keep a reference is rather
risky and not defensive at all.

Especially dma_buf_poll got that horrible wrong, so better
remove that sentence and also clarify that the callback
might be called in atomic or interrupt context.
