[PATCH RFT] sparc: dma-mapping: support debug_dma_mapping_error

[Shuah Khan]

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.
