dmaengine: ioat: set error code on failures
In function ioat_xor_val_self_test(), when the calls to
dma_mapping_error() fail, 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.
