[Intel-gfx] [PATCH 2/2] dma-buf: Fix dma_resv_test_signaled.

[Maarten Lankhorst <maarten.lankhorst@linux.intel.com>]

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.

Fixes: 7fa828cb9265 ("dma-buf: use new iterator in dma_resv_test_signaled")
