dma-buf/dma_fence_array: remove unused functionality v4
Amdgpu was the only user of the signal on any feature and we dropped
that use case recently, so we can remove that functionality.
v2: update num_pending only after the fence is signaled
v3: separate out simplifying dma_fence_array implementation
v4: fix XE patch split fallout
