dmaengine: ioat: set error code on failures
In function ioat_dma_self_test(), when the calls to dma_mapping_error()
fails, the value of return variable err is 0 (indicates no error). As a
result, the return value may be inconsistent with the execution status.
This patch fixes the bug by assigning -ENOMEM to err on the error path.
