dma-mapping.h: preserve unmap info for CONFIG_DMA_API_DEBUG When CONFIG_DMA_API_DEBUG is enabled we need to preserve unmapping address even if "unmap" is a no-op for our architecutre because we need debug_dma_unmap_page() to correctly cleanup all of the debug bookkeeping. Failing to do so results in a false positive warnings about previously mapped areas never being unmapped.
