md/raid6: cleanup ops_run_compute6_2
Neil says: "It is correct as it stands, but the fact that every branch in the 'if' part ends with a 'return' isn't immediately obvious, so it is clearer if we are explicit about the if / then / else structure." Signed-off-by: Dan Williams <dan.j.williams@intel.com>
