When starting streaming the driver currently programs the buffer address to the CAL base-address register and assigns the buffer pointer to ctx->dma.pending. This is not correct, as the buffer is not "pending", but active, and causes the first buffer to be needlessly written twice. Fix this by assigning the buffer pointer to ctx->dma.active.
