[PATCH RFC] dma-buf: To check DMA_FENCE_FLAG_ENABLE_SIGNAL_BIT status on debug

If core DMA-buf framework forgets to call dma_fence_enable_signaling() before calling the dma_fence_is_signaled(). To handle this scenario on debug kernel the DMA_FENCE_FLAG_ENABLE_SIGNAL_BIT needs to be checked before checking the actual signaling status. Signed-off-by: Arvind Yadav
