Revert "dma-mapping: clear dev->dma_ops in arch_teardown_dma_ops"
This reverts commit 46053c73685411915d3de50c5a0045beef32806b. This change breaks architectures setting up dma_ops in their own magic way and not using arch_setup_dma_ops, so revert it. Reported-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Christoph Hellwig <hch@lst.de>
