Tom Barber updated OODT-572:

    Attachment: fix_mkdir.patch

Picked what I hope is an easy jira to start.

Fixed both the occurrences I could find.

> From Albert Y Chang at JPL:
> We have been seeing intermittent (non-repeatable) ingest errors (Destination … directory
cannot be created) from LocalDataTransferrer which we believe occurs when multiple ingest
processes are copying files to the same not-yet existent repo directory; there's a race condition
to make the same parent dirs, and all but the first fails.
