dmaengine: dmatest: fix a small memory leak in dmatest_func()
We recently moved the test size tests around but it means we need to
adjust the error handling as well or we leak the "pq_coefs" memory. I
updated the label name to reflect that we're freeing coefs.
Fixes: 787d3083caf8 ("dmaengine: dmatest: move size checks earlier in function")
