[PATCH 6/9] dma-buf/dma-fence: Allow wait_any_timeout without default_wait

[Jason Ekstrand]

dma_fence_wait_any_timeout only relies on two things to work correctly:

 1) The SIGNALED flag to be set upon fence signal
 2) The callback list to get called upon fence signal

Both of these are part of the core dma-fence API so it should work fine
even with a non-default wait function.
