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.

Marek/Jonas,

This one is for openrisc to go through Marek's tree with the other arch
debug_dma_mapping_error() patches. Hoping it is ok with Jonas.

Thanks,
