Subject: [PATCH RFT] powerpc: dma-mapping: support debug_dma_mapping_error

Add support for debug_dma_mapping_error() call to avoid warning from
debug_dma_unmap() interface when it checks for mapping error checked
status. Without this patch, device driver failed to check map error
warning is generated.

This one is for powerpc to go through your tree with the other arch
debug_dma_mapping_error() patches.

Thanks,
