Along with the transition to the managed PCM buffers, the driver now accepts the dynamically allocated buffer, while it still kept the reference to the old preallocated buffer address. This patch corrects to the right reference via runtime->dma_addr.
(Although this might have been already buggy before the cleanup with the managed buffer, let's put Fixes tag to point that; it's a corner case, after all.)
