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
