drm/ttm: Use dma_fence_check_and_signal()

The return code of dma_fence_signal() is not useful and shall be removed
from the kernel. To do so, the few users who rely on the return code
must be ported.

Use dma_fence_check_and_signal() and mapp its boolean return code to
dma_fence_signal()'s former value for already-signaled fences.
