dma-buf: fix dma_fence_array_signaled v4
The function silently assumed that signaling was already enabled for the
dma_fence_array. This meant that without enabling signaling first we would
never see forward progress.
Fix that by falling back to testing each individual fence when signaling
isn't enabled yet.
v2: add the comment suggested by Boris why this is done this way
v3: fix the underflow pointed out by Tvrtko
v4: atomic_read_acquire() as suggested by Tvrtko
