Commit 7fa828cb9265 ("dma-buf: use new iterator in dma_resv_test_signaled")
accidentally forgot to test whether the dma-buf is actually signaled, breaking
pretty much everything depending on it.
NAK, the dma_resv_for_each_fence_unlocked() returns only unsignaled
fences. So the code is correct as it is.

Christian.
