mpt3sas: Call dma_mapping_error() API after mapping an address with dma_map_single() API
Added dma_mapping_error() API after mapping an address with dma_map_single() API. Otherwise when CONFIG_DMA_API_DEBUG is enabled in the kernel, then it complains about mpt3sas driver not calling dma_mapping_error after mapping an address with dma_map_single Signed-off-by: Sreekanth Reddy <Sreekanth.Reddy@avagotech.com> Reviewed-by: Martin K.
