Issue 6207 - Random crash in test_long_rdn CI test

[progier389]

CI test indexes/test_long_rdn sometime crashes The issue is that a data returned by dblayer_bulk_nextdata iterator is wrongly freed The fix is to avoid freeing the data

LGTM as well. Just a minor comment. Sometime the function _entryrdn_dup_rdn_elem is called before _entryrdn_resolve_redirect so that this later is called with '1' (canfree). For example here or here

In the opposite here or here

You may use the same way of calling everywhere.

I agree it would make things more readable, but on the other side it will duplicate the rdn_elem when it is not really needed (then you will have to take care to free the duplicated data) and I would rather prefer to avoid stressing malloc/free when it is not useful.
