dmaengine: Fix dma_slave_config.dst_addr description
The dst_addr member of the dma_slave_config structure has been mistakenly marked as ignored if the *source* address belongs to the memory. That is relevant to the src_addr field of the structure, while the dst_addr field contains a destination device address that should be ignored if the destination is the CPU memory. Correct the @dst_addr description accordingly.
