Mount option index=on checks on mount that upper dir is not being reused with a different lower dir than the first lower dir it was mounted with. This behavior is verified by test overlay/037. In this test however, it is not desired to fail mount on mismatch of upper/lower, so use the matching upper/lower dirs in this test. The mismatch went unnoticed because the index=off mounts do not verify lower dir and the index=on mounts fails on EBUSY (dir in use by another live mount) before failing on ESTALE (upper/lower dir mismatch). Never the less, fix the mismatch, so a change in the kernel between the two sanity checks (EBUSY vs. ESTALE) won't break the test.
