dma-fence: Clear fence->status during dma_fence_init()
As the fence->status is an optional field that may be set before dma_fence_signal() is called to convey that the fence completed with an error, we have to ensure that it is always set to zero on initialisation so that the typical use (i.e. unset) always flags a successful completion.
