Channels allocated via dma_get_any_slave_channel were not increasing the counter tracking private allocations. When these channels were released, privatecnt may erroneously fall to zero. The DMA device would then lose its DMA_PRIVATE cap and fail to allocate future private channels (via private_candidate) as any allocations still outstanding would incorrectly be seen as public allocations.
