Thomas Hellström 45c74f4f54 dma_fence_array: Fix PENDING_ERROR leak in dma_fence_array_signaled() 
commit 95d3583888 upstream.

If a dma_fence_array is reported signaled by a call to
dma_fence_is_signaled(), it may leak the PENDING_ERROR status.

Fix this by clearing the PENDING_ERROR status if we return true in
dma_fence_array_signaled().

v2:
- Update Cc list, and add R-b.

Fixes: 1f70b8b812 ("dma-fence: Propagate errors to dma-fence-array container")
