dmatest: correct raid6 PQ test
The number of PQ sources specified by module parameter "pq_sources"
is always forced odd to fit into dmatest's destination verificaton
scheme. But number of PQ sources and coefficients as passed to the
driver's prep_dma_pq() is not adjusted accordingly.
Fix it now to get correct PQ testing results in the case passed
"pq_sources" parameter is even.
