tools/cephfs/DataScan: cleanup debug prints

So it doesn't look like:

    2025-01-29T18:47:36.592 INFO:teuthology.orchestra.run.smithi043.stderr:2025-01-29T18:47:36.583+0000 7fc310d1e840 20 datascan.find_or_create_dirfrag: Dirfrag already exists: 0x0x10000000000 *

or

    2025-01-29T18:47:36.589 INFO:teuthology.orchestra.run.smithi043.stderr:2025-01-29T18:47:36.578+0000 7fc310d1e840 10 datascan.find_or_create_dirfrag: Created dirfrag: 0x0x1
