dma-direct: fix DMA_ATTR_NO_KERNEL_MAPPING

The new DMA_ATTR_NO_KERNEL_MAPPING needs to actually assign
a dma_addr to work.  Also skip it if the architecture needs
forced decryption handling, as that needs a kernel virtual
address.

Fixes: d98849aff879 (dma-direct: handle DMA_ATTR_NO_KERNEL_MAPPING in common code)
