Oded Gabbay 4518cd28d8 dma-fence: add comment for WARN_ON in dma_fence_release()
In dma_fence_release() there is a WARN_ON which could be triggered by
several cases of wrong dma-fence usage. This patch adds a comment to
explain two use-cases to help driver developers that use dma-fence
and trigger that WARN_ON to better understand the reasons for it.

v2: change to a more generic, one-liner comment
