[PATCH 08/12] xfsprogs: ensure dup table always has entry for obfuscated name

[Alex Elder]

We need to ensure the name table has a copy of all the names in
a directory in order to avoid creating duplicate entries when
obfuscating names.  Currently there is an (unlikely) case where
the name is passed back without such an entry being created.
Reorder things so that won't happen.
