[ Upstream commit92f853f064] In dma_release_channel(), check chan->device->privatecnt after call dma_chan_put(). However, dma_chan_put() call dma_device_put() which could release the last reference of the device if the DMA provider is already gone and hence free it. Fixes it by moving dma_chan_put() after the check.
