Currently there are three valid implementations of dma_mapping_error:
(1) call ->mapping_error
(2) check for a hardcoded error code
(3) always return 0
This patch provides a common implementation that calls ->mapping_error
if present, then checks for DMA_ERROR_CODE if defined or otherwise

Currently there are three valid implementations of dma_mapping_error:
(1) call ->mapping_error
(2) check for a hardcoded error code
(3) always return 0
This patch provides a common implementation that calls ->mapping_error
if present, then checks for DMA_ERROR_CODE if defined or otherwise
