BufferQueueProducer: fix which slot gets pre-allocated

Commit 78014f32da6d0ebf52fb34ebb7663863000520a0 introduced a bug that
made us pre-allocate buffers into the last available free slots instead
of the first available ones. This in turn caused more re-allocations,
and possibly triggered driver bugs.
